Yes, Ben is acting like an ear penis, although I do have some understanding for him being resignated to seeing drug using kids after working in that scene for a while. Maybe being an asshole is how he managed to stay with Amara for so long. It would of course be the right thing to get more involved in his life, but I get the feeling Amara is not the type who'd want to let anyone in, and would probably be (more) offended if Ben tried getting closer to him.
Aria on the other hand seems to crave a caring parental figure who breaks through his walls and shows him some boundaries. It's a part that Amara, the only other person he's close to, won't be able to fill...
That link wants me to log in to Microsoft. Is it supposed to be like this?
