Miles (spoilers)
I loved Miles this season. Eric is able to portray such an emotional vulnerability that makes me really care about Miles even when he's being obnoxious and/or self-destructive. I especially loved the last episode with him and Hunter. I think he saw a distorted mirror image of himself in Hunter realizing that they both have a lot of issues to work through. All I know is Miles can't leave for boarding school because he has become my favorite character and I would really miss him if he goes...Esme can leave though!
The one thing that bugged me though is that if someone genuinely has anxiety it's okay to take meds for that and I would hope that Miles' doctor would prescribe him something. It almost seemed to be insinuated that he can't take meds at all but he can as long as they're prescribed, he doesn't abuse them and he still sees a psychiatrist and possibly a psychologist on a regular basis.
