Ellie probably acted like she loved school so people didn't catch on. She doesn't really HATE them, she's just bad at them. But I'm sure when she was feeling down, she jumped on that hard. I think it'd be hilarious for them to be friends. She'd be both equally loving and WTF R U DOING, FI. Hm? Hm?
Ooooh! Yeah! I could see them getting along. Or, at least, see her bugging the crap out of him, if not just because she's like... your face is the babiest-looking face I've ever seen on a human. So yeah, she's gonna glomp on this kid.
