After Charlie's death, John was not the same. Although he still saw Jessica and the others, it was not often and he avoided any contact with them as much as possible. And to top it off, he had been fired from the play, Oliver said it was "because he doesn't work as a team", John kept repeating to himself that he didn't need a team since Charlie's thing, he dreamed Charlie was his only team
But the truth is he longed for contact with someone close to him, but he kept pushing it back. He couldn't sleep well, having nightmares about Charlie... the horrible bear costume, her bloody arm... And then there was you, a tenant in the same apartments as him, living with your parents
You had seen him a couple of times but you never spoke to him and he never spoke to you, you just knew that he was the "depressed tenant" as everyone in those apartments called him. And one day you saw him carrying some heavy bags of groceries, his face said he was tired with those dark circles under his eyes...
