Flowerpot Dumbles makes an appearance, glaring at Harry and screaming, "What the fuck!"
He grabs Harry by the arm and starts dragging him towards a portal. Narcissa runs into the room and sees the commotion. She fires off a spell, sending Flowerpot Dumbles back through the portal, releasing Harry.
"Oh, no," Narcissa Whispers into an utterly confused Harry's ear. "That crazy old bastard won't ruin my happy ending!"
Meanwhile, back in his own time...
Flowerpot Dumbles lands in an undignified heap on the floor of his office. Fawkes stares at him and starts laughing.
Foiled Again, Flowerpot Dumbles thought to himself.
Flowerpot Dumbles looks around and starts throwing a fit. "Goddamnit, that idiot boy is going to fuck up my happy ending!"
