[@Kale19] It's not all bad, though. A lot of your post is fine. Here's an example of a good edit, though you can do something different if you want:

	Lily looked eagerly up at her brother. It was not every day that the supers of America met. Lily had developed her powers quite recently, when the family discovered she could float on water, like her namesake, the lily pad. Since both children got their powers less than a week ago Kael's parents were a little nervous to send them off on their own. Of course, after Kael promised nothing bad would happen, and flashed them a grin with his Venus-flytrap-esque teeth, they allowed him to go.

	Once their parents had dropped them off he made Lily promise she wouldn't leave. Of course that promise was broken as soon as she saw the dog. She ran off to pet the German shepherd. Chasing after her Kael slammed into a woman checking her purse. As he apologized he noticed the ram's horns sticking out of her head.

	After weaving through person after person Kael finally found lily, approaching a man who he didn't know. Pulling his sisters arm disappeared into the crowd.
	
	"Don't talk to strangers, Lily."
	
	"He's not a stranger, he has a dog!"
	
	"Just because he has a dog doesn't mean we've met him before." Kael explained. "Come on, let's head over there." Kael said pointing to a corner at the area. "We'll take a second to talk."
	
	"About what?" Lily asked.
	
	"Stranger danger." He muttered.
							
	Soon he and Lily were heading to the conference hall get seats. [Insert another cool-looking unnamed NPC] was talking to Lily, who had somehow snuck up to sit next to her. Going over to grab Lily Kael passed the ram-horned woman, who gave him a confused look. In return Kael gave her a Flytrapy smile.
	
	"Lily we just talked about this, you can't talk to strangers." 
	
	"But this isn't a stranger this is-"
	
	"If you know her name that doesn't make her not a stranger." He explained. Turning to face the girl he said sorry.
	
	"Oh, no problem at all..." She said seemingly asking for a name.
	
	"Kael, Kael O'Conner. Now C'mon Lily let's head back to our seats."



---- If you don't like the lack of interaction with other player characters, another option is to go up to the group and introduce yourself (or have Lily do it) in a way that doesn't control other people's characters. ----
