Remus was surprised at Harry's no, "Harry, this man..." He started.
"I know what he is. But we'll take him to the castle." Harry was going to be sensible, he wasn't going to just take revenge.
"Bless you, boy! Bless you..." Peter grovelled, touching the boy who lived.
"Get off! I said we'd take you to the castle. After that, the Dementors can have you." Harry sounded angry, even though he wasn't going to let him be killed here didn't mean he was forgiving the rat.
