[@Ejected] I think it would be interesting if they both just happened to enjoy a similar space for their away from other people time. Like the ____ corner of the library where they both know it's the most quite. They kind of just know each other from random comments, maybe chatted once or twice, but otherwise just know of each other by name/house/year/etc...

With Honey I would assume they wouldn't know each other. She's probably just the "cool" girl on the Slytherin team to him :P
