Sometimes, when Erik is alone at night, he closes his eyes and thinks about Charles. He tries to remember his face, his smile, the feel of the tweed jackets under his hands, but he rarely can. He’s a memory so far away from him that he cannot reach it, even if it’s the thing he wants the most.
So he thinks about going to Raven, to beg her to turn into him. But he never does. That would be a lie, and lies are not accepted.
One time Raven tried turning into Charles to see if her brother and Erik were talking about something the kids didn’t know, those times (a lot of times) when they were alone. She went to Erik looking like Charles, imitating her brother like only a sister perfectly can.
Erik then smiled at her and called her out on it. She asked him how he knew and he told her that, when he was around Charles, he could always feel his mind in the back of his own, even when he wasn’t using his abilities.
