"Hmm, Sarah Jane, what is it?"
"K9's found something."
"Oh, what, K9 what have you found?"
"Greetings, Master, there is a slight invergence of the gamma emitters."
"Are you sure?"
"Affirmative, Master."
"What does that mean, Doctor?"
"Well, I'm not quite sure."
"Twenty minutes until destruction, Master."
"Oh, that isn't good."
"Doctor, what's happening?"
"I'm afraid we've had it, Sarah."
"What?"
"Catastrophic collapse of the manifold, inevitable in afraid."
"Doctor! What do we do!?"
"Hahaha"
"Doctor."
"Hahaha."
"Oh, you're playing one of your jokes on me again."
"Well,"
"Fifteen minutes until destruction, Master."
"Doctor?"
"Ah, yes, well, there is a problem, I just have to fix it."
"Oh, Doctor."
"Sarah Jane."
