"...Holy shit," says Feral.

Tony is also staring.

Sherlock is curled up next to Tony, not doing much of anything at all.

Feral emerges from Tony's lap and attempts to give the glowy person a hug, despite the obvious insubstantiality problem.

"What the fuck just happened," says Feral, hugging her.

"Yeah. What he said," says Tony, hugging Sherlock.

"I killed it," Bella says. "It's gone."

"How, though."

"With a - super-Patronus. I wasn't sure if it would work but it worked."

"What did you actually do, is what I'm trying to get at here," says Tony.

"I sort of - you know how I got mist when I thought about the right books - I just thought about - I'm not sure how to put it in words."

"...Oookay," says Tony. "Bella has Special Patronus. Got it."

"I'm pretty sure I could do it again, now that I know I can."

"...You're gonna want to go around slaughtering Dementors now, aren't you."

"Of course!"

Feral hugs her some more.

Hugs. "I will need to think of a way to go to that British prison without getting arrested. And then I have to find out how to find wild ones. But I'm going to get them all."

"...I could fly you places," Feral offers. "Thestrals are good at finding."

"That would be great," Bella says.

"I wonder if I can work from far away. Maybe I should try sending my glowy person to Azkaban from here. You know, with a message. For the dementors. 'Goodbye forever'."
