(Please tell me if anything needs to be changed or if I should add anything else.)
Katherine Anne PrydeNothing but respect, if not a tad bit of intimidation. Who knew such vast intelligence could be so intimidating. However, Harley does his best to keep on her good side, if not attempt to impress her with his own studies and intelligence. If he has a chance of getting into a good college, while also controlling his powers, it's under her guidance and tutelage. Not only that, but she serves as a good role model to aspire to, and though her powers don't seem like they would a danger to others but herself, the way she can control them instills hope and confidence that he could become that proficient in using his own.
Harley's not talked to her much, but due to his sister having accosted her so much to admit him and help him, he's certainly on her radar. Out of most of the candidates, Harley's ability draws a lot of concern for the well-being of both the students and faculty. If anyone has to potential to fall further than they already have, it's probably Harley. Every power has a dark side, but Harley's is blatant enough to warrant further caution.
Armonia TorresArt isn't really a subject that Harley is proficient in, or has much passion in, but Armonia just has the way of talking and teaching that makes you believe in it, if that's the right phrasing. Harley can't really explain it, but he's never been more enthralled with an art class than he has when Art is teaching it—a very apropos name, he's regarded plenty. And though he doesn't often talk, Mrs. Torres is nothing but sweet to Harley, as if she kind of understands the pain he keeps locked up inside. Artwork isn't something he necessarily wants to find work in, but when he's feeling down or just out of it, which is a lot of the time, he can always look forward to expressing that through his artwork. Armonia has become somewhat of a silent confidant, in that she's given him a way to vent properly and safely and, though he's particularly shy about talking to teachers, he would love to let her know how big of a role she's played in helping him. If not to control his powers, but to properly understand himself and his feelings, and giving him an outlet for the things he's bottled up since birth.
Daisy VaughnHarley exercises regularly, but fighting isn't necessarily one of his strong points. Though, he takes Daisy's classes as seriously as possible primarily because he'll need to find a way to enhance his own skills, if he wants to survive outside of the Institute. He's a fast learner and does his best to properly study outside of class; in fact, all he has time for is studying. As well, he figures if he knows how to control and defend himself, then doing the same with his powers will come more naturally. He's got a lot of respect for Daisy, as he does all of the teachers, and her strong hearted, but sweet nature comes off as very helpful and amicable to Harley. He's not particularly close to her, but she's among the many teachers he can confide in, if he every brings himself to do so.
Steve IrvineHistory hasn't always been a strong subject for Harley, but he does his best to keep within Steve's good graces. Of course, there's not much he can say about Steve as he purposely attempts to avoid any interaction with him; the man seems too friendly and Harley's not one to get too friendly with really anyone. There's always something about talking to authority figures, especially ones that try to relate to their students. The only thing Harley really has in common with Steve is the fact that they're both mutants, other than that, there's really no reason that Harley feels the need to talk to Steve, other than to participate in class and ask questions like a regular student. But, even that is kept to a minimum.
Marlowe FaradayIf there had to be a teacher that he fancied more for his looks than anything else, Harley would be ashamed to say that Mr. Faraday is that teacher. But, other than that, Harley enjoys science as a subject and does his best to preform as well as possible in and outside of class. There's something about Marlowe, however, that either brings Harley slightly jealous or inspires him, and it probably has to do with how sure Marlowe is about himself and what he's saying. There are plenty of teachers to be inspired by for the tact and control, and Mr. Faraday is one of them. And there's no other teacher he feels the need to impress and whose disappointment he fears, other than Mrs. Pryde, than Mr. Faraday.
Inside of class, Harley is the perfect student and is truly interested in the subject that Mr. Faraday teaches. Outside of class, Harley has a relatively hard time approaching him for anything other than classwork, which is natural for him, but Marlowe, along with a lot of other teacher he wishes to confide in, has a set of talents that could possibly help him achieve his goals. He truly wants to end his senior year able to fully control when and where his powers activate and he intensity of such. Marlowe's combat prowess and general confidence is like one of the many lighthouses for him to work towards.
Freddie DiAngeloPhysical Education, despite Harley's aptitudes, has never really been a problem for him and it still isn't, to be honest. However, Freddie is probably the most intimidating of all the teachers and scares Harley the most. Like Steve, Harley does his best in class, which in P.E. isn't hard for him to accomplish, but outside of it, he often makes a fool of himself trying to avoid any contact with Mr. DiAngelo. Put Harley and Freddie in a room together and he'd probably start clawing at the door and screaming for someone to let him out. What more, Freddie should be even more volatile around Harley, due to the nature of Harley's powers, and that scares him even more. Though, even without his powers causing a mess for him, he'd probably still attempt to avoid interaction with Freddie, at all costs.

Luna MarionetteDue to the nature of Luna's powers, Harley has made an effort to avoid interacting with her. Not only does she lack the control of an expert, but he's in the same boat as her. Mix those two together, and you've got a gal with fully unlocked potential under an insatiable bersker rage causing mayhem and destruction wherever she pounce. To that effect, Harley doesn't know Luna too well and doesn't try to. As such, he can come off as a little too cold and distant, as if he has an actual problem with her. Though, if asked he is more likely to tell her the reasons in person, rather than lie about it. But, that opportunity has not presented itself and he's not found the right moment to right any small rumors going around about how he feels about her. Most of all, he fears that the whole avoidance thing is going to blow up in his face and when it does, he only hopes there are people around to stop that from happening.
Duncan SpencerBoth are rather distant, though Duncan is of the colder variety, but if there's anyone who could still be affected by his powers and go relatively unharmed, it'd probably be Duncan. That and he'd probably not really care about what just happened to him for the last 30 or so minutes. But, their personalities are relatively alike, which means they don't really find the necessity to talk to each other. Though, Harley can safely say that the two are on good terms—Harley likes to think he's on good terms with everyone. Duncan's also not that bad to look at and he's relatively isolated enough to get a good view. Of course, why would Harley admit anything like that. Any relationship that ever forms between them would probably be very platonic, but that doesn't mean attraction is totally out of the window. Right? Harley's not very experienced when it comes to the touchy feely aspects of relationships, much less relationships in general.
River HunniganWell, there's not much to say about Harley and River's relationship because there really isn't anything aside from the odd hellos down the halls. There's an obvious troublemaker vibe coming off of River that Harley would really want no part in, but that doesn't mean anything in terms of interacting with him. It just means he's most likely to say no to any offers of graffiti or smoking a joint or causing mayhem around the town. They don't have much to relate on, so Harley doesn't push any further than just be a polite acquaintance, like he does with most people. He likes River, he likes everyone, but he doesn't like socializing outside of his comfort zone, so if anyone had to initiate conversation, it'd probably be River.
Naka VejayCurrently doesn't know who Naka is.Alicia TaylorLuckily, Alicia's powers don't affect other mutants... that would be rather bad if she had take control of Harley through some unfortunate mishap. That would be pretty bad for everyone, actually. There would be no tell what she would effectively cause them. He, however, makes sure to keep her distance when they talk; his powers have been known to further enhance other mutants and who knows how far Alicia's powers could go. But, she's social and friendly and he does his best to keep up with her when she approaches him. Other than that, he's not a fan of talking and often wishes their conversations would go by a little quicker, not out of some underlying misanthropic hate, but more out of just being outside of his comfort zone for too long. They're decent relationship wise, but Alicia probably understands that Harley has his limits when it comes to other people.
Oona FredrickOona's clingy nature is very, very off-putting to Harley, so he does his best to draw a line between them in order to keep her from getting a little too close for Harley's comfort. She's a nice gal and all, but clingy and Harley just don't mix... like, ever. His often quietness can come off as cold, so that helps to draw a bit of distance between them. He'd love to keep their relationship at relatively close-ish acquaintances, if that's even possible
Alucard De VinciYeah, when confidence kind of goes over the line, it comes off as arrogance and Harley's not a fan of people who are too sure of their abilities. If they know where they're going in life, what they're capable of, but also respects those around them, then that's a good balance of confident, but still humble. Something about Alucard just rubs Harley the wrong way, whether it's the fact that he's pretty much a walking vampire or his deluded sense of righteousness, he doesn't quite know. There's way too much grey in the world to force oneself to look at things from a black and white perspective. So, Harley does the minimal amount of interaction when Alucard comes into the picture, and he's pretty adept at not socializing with people if he doesn't want to. Not only that but his powers don't quite mix well with insatiable blood lust.
Harley CoemanOoh, there's no one he dislikes more than himself. Sad to say, but if there were anyone he'd want to be, it'd be anything but who he is now. Harley himself treads a very thin line and can honestly go either way with the proper (or improper) nudge and he knows it. That's what scares him. He could control his powers and become something he could only dream of, or he could let it overwhelm him and be the thing he's worked so hard against.

Daniel GreenThey have a few things in common, though Harley isn't necessarily timid—at least that's not what he thinks he is. Danny kind of encompasses all there is to love about nature, though all of nature is a bit much for Harley. He'd rather find a good balance and does so with bugs and animals, in general. They don't talk much, but when they do it's usually about the subjects and things they have in common and it's really one of the only types of conversations he appreciates. There's not really many people in the building that share his fascination with animals, much less the insects or arachnids that he fancies. But, Danny's just a kind of friend, just like everyone else to him. If he had a choice between talking to Danny and spending time alone in his room, he'd almost always pick the room. But some people are little harder to subtly push away than others.
Jade GreenThey both work at the animal shelter and they're both pretty scared of their powers. Of course, anything beyond having class and working together could possibly spiral down into a lot of terrible things. Of course, in the institute, they have plenty of people there who could contain the situation, but outside of that sanctuary, there's not much to stop any mayhem that could ensue. So, Harley doesn't associate with her unless it's absolutely necessary. He doesn't know her that well and the same goes for her, but she seems nice, if not a little scared of herself. But, in order to help someone else, he must first help himself... and there is a lot of help that he needs to do in order to even be considered remotely safe.
Aurora ClaudwellHarley likes Aurora, but like everyone else, he does his best to keep the distance fairly open and rather far. He doesn't know much about her, but from observations she seems to hold a lot of weight on her shoulders, though she seems to get relatively lighter every passing day. It's nice to compare when he first met her to how he sees her now, but her spontaneity and how close she tends to get to others is off-putting to Harley, for the same reason he gives for distancing himself to everyone. Though, when she does get close enough to him, he enjoys her wild spirit and her smile can be infectious, even if he's not willingly participating in the interactions. They friends, but not close enough for Harley to be concerned.
Adrien TimoshenkoAdrien is a nice fellow, but is too close to him for his general comfort. What he could do with all that stuff pent up inside him, should he ever lose control of himself. But, Harley doesn't necessarily know how much his powers affect Adrien, though he wouldn't like to test any of his theories. He likes to keep Adrien thinking that they're pretty close friends, but in reality, Harley often finds himself purposefully drifting away from him whenever he gets the chance. Luckily, he usually forces himself to get swamped with schoolwork, not short of asking teachers for extra assignments, so it gives him the proper excuse to avoid Adrien without really raising any suspicions. He's a nice guy though, and he appreciates his effort, but Harley's much too used to being alone and is far from allowing himself to potentially put others in danger, regardless of whether or not Adrien is immune to his powers.
Elena ElwynHarley doesn't know Elena all that well (Not sure if she's new or not.)Flavie LefèvreDue to Flavie being a new arrival, Harley hasn't gotten a good opinion of her yet.Morena Silicus(Don't know if she's new or not either, but will gladly change to add any thoughts, etc.)
