I mean she obviously doesn't know Ezra at all, wow. (This is both sarcasm and kinda true just cause he was gone when she was so little lol >.>)
I figure she's met at least with Killer Frost, Aranea, Allison, Jacen, and Lucy at least at this point? And she'd obviously know who Thea is at least. But probably bonded the most with Lucy and Allison and Jacen. Just since she's come to uhhhh laser tag and camping. I think laser tag was the other thing we said she was at whilst you were ~INJURED~.
