Meanwhile, Trever has his own brief moment of confusion when he sees the red haired woman in front of him. His automatic reaction is to shoot them.

Because in his family it's either shoot first or get shot.

So, with very good aim, Trever shoots Ginny in the chest with some fantastic green dye as he says in confusion, "Una?"

Before it catches up with him that she just called him "William" and not "Trever".
