Well, we know that Amy's only relative left is Chris, and while they don't know why he seems to be so reluctant to care for her, we know he has a very good reason.
He has a problem 3 days out of the month. That's pretty much it. Chris doesn't even
try to make it work. He couldn't be bothered to spend time with her when she was upset and recently released from a mental hospital, but he could be bothered to go out for drinks. Sorry, that doesn't fly with me. Find a way to make your life and your problems less intrusive and deal with it.

And, Hallie's parents had recently died (I think it was a car crash) and Prof. Stokes was her uncle. I forget just how it came about that they took her in, but (aside from the fact that we know what a weird place it is), it would seem that the Collins family could offer more for her than her uncle.
In the first place, the Collins family is not Hallie's family. Stokes is. The people down the street might have more to offer a child than his or her own family, but that doesn't mean they should take the kid in. He's a frigging college professor. We've seen the character's home and it doesn't seem like he's suffering financially. Yeah, it also looks like a single bedroom residence, but under the circumstances, you'd think the man would move into something larger and step up to the plate.
Let me put it another way. Young girl loses both of her parents in a violent accident. Wrenched away from her environment to strange new place. Her only relative can't be bothered to make the needed adjustments to take care of her and dumps her with strangers, kind strangers, but still not people she knows.
Sorry, to sound so passionate about this, but it's just not right in my book.
