Erik's thoughts are perhaps not surprising but not helpful, especially as he notes how Erik's hair changes and loosens. He wonders what else his hair would do, its always so controlled like him.

As he cannot act on these thoughts, Charles ever so slightly fidgets and feels as more of a fool.

He pulls his hand out of his pocket and runs it through his hair as a way to not look.

Its a move that reminds him of being a teenager and trying to figure out how to do anything with someone he liked.
