A potentially explosive situation

"Well, the bomb is still counting down," said Buffy. "Shouldn't one of you three be doing something?"

"Hey," said Willow to the naked future Clara Oswald. "Why doesn't your Mistress Missy do something?"

"Missy is not my Mistress," said future Clara. "She's my --"

"Oh, I can speak for myself, Clara," said Missy. "Because if worse come to worse, I can always regenerate," said Missy. "While you humans -- well, normally this would be the ideal time to prove your problem-solving skills to me, but apparently you have none. What a pity."

"Hey, why is that version of Clara naked?" asked Amy. "And why are there two Claras anyway? Because we just brought another version of --"

"Amy," said Buffy. "The bomb. If you, Willow or Tara know of a spell that would stop it, I'd greatly appreciate it if you stop playing twenty questions and concentrate on keeping us all from getting killed."

"Why don't we all escape in the TARDIS?" asked Tara.

"Because you'd never get away in time," said Missy. "Anyway, I knew you so-called witches would not be able to do anything. First, the Slayer struck out trying to move that thing and now you three just --"

"Wait a minute!" cried Amy. "Who says we can't do anything?"

She turned toward the Dalek and started muttering a chant in Latin, all the while pointing at the floor.

"Er, Amy," said Willow. "I don't think it's going to help matters much if you turn the Dalek into a rat."

"Hush, Willow," said Tara. "Let the girl concentrate. And anyway, it's not like I have any ideas. How about you?"

"Well, I tried to stop the countdown with magic," said Willow, "but nothing I know seems to work."

"How about putting the bomb in a time loop?" asked Tara.

"Er, you really don't want to do that," said future Clara. "You really don't -- Hey, don't tell me that what's your friend Amy is going to do? Surely she's not that stupid."

"No, she isn't," said Tara. "And please stop calling her Shirley."

"I wasn't -- Oh, I see," said future Clara. "It's a joke."

"Got it," said Amy as she finished the chant.

"But the Dalek is still counting down," said Willow.

"Whoever said I was casting a spell on the Dalek?" asked Amy.

Just then a blue glowing hole opened in the metal floor just beneath the Dalek. The Dalek promptly fell into the hole just as it reached the number two. It promptly disappeared from sight within the hole and then Amy immediately made the hole vanish with a wave of her hand.

"There," said Amy. "Problem solved."

"No, it isn't," said Missy. "You just sent it somewhere else."

"Where did you send it?" asked Willow.

Amy shrugged. "I don't know. Just somewhere other than here."
