Harry's mouth drops open the moment she said there was no Percy Weasley. "Merlin," he exhales and looks at Hermione before looking at the professor again. "She actually sacrificed one of her children for this."

He couldn't even fathom it. Though, truthfully, he hadn't thought of his own children since they arrived in the past but as far as he saw it... they weren't really his children. Which was perhaps harsh but how he felt.

After a moment, he mentally gathered himself again. "That is unfortunate," he said finally. However, it did help in some way. Percy wouldn't be able to assist Barty Crouch Jr. later on in their Fourth Year with the tournament. "We are coming to you, Professor because the first time around we were both in your house and came to trust you and look up to you. We know how rapidly things can and will go down and will need your help. The first is a rat that young Ronald has in his possession." He hoped Ron had him anyway. Scabbers had been Percy's before.
