Roy slipped away from his mentor. He wanted independence, to be on his own and to be recognized, that's why he urged urged himself to leave his friends as well, growing distant from them.

He wasn't he same. It was like he was forcing a wall in between his friends, every problem he had, Roy wouldn't ask help, he wanted to be able to do all by himself.

It all came up to him, of course, pent up somewhere in his hasty mind, then to his result, there was no one he could call on. He didn't leave his place today, but who would notice anyway? He barely talks to them, specially to Oliver, not because he despises them but because he doesn't need them, needed, now past.
