Of course he worries about it. Billy knows just how he ended up with his mother abandoning him. But there were differences. He'd been older and known her better before she left. And there had been Neil. If one thing had always been clear, it was that Steve Harrington was most definitely not like Neil Hargrove.

I need to feel warmth baked into my skin, I need to be able to retreat to the waves. Some days it feels like it's the only thing keeping me sane. Like the art isn't enough."
