Billy is slowly catching up to what they're talking about, and when he realizes who the her in question must be, he understands why Erik is so hell bent on stopping the event from happening. He almost wants to interrupt again, try to do something to save her, but Charles is right. They've done it both ways and nothing has happened.

It's hard to picture the thin, devastated boy as the man he'll become, especially when all Billy wants to do is take him in his arms and make false promises that everything will be okay.
