The TARDIS has a problem with Ruby Sunday

"Is this really necessary?" Ruby asked, frozen in place.

The TARDIS was currently holding the teenager in stasis, suspiciously scanning her.

The time machine had started blaring out alerts the moment they had returned to the ship from their latest adventure, and she only quietened once the Doctor allowed her to perform a scan on their newest companion.

"Sorry, Rubes," the Doctor said, "but she's being really temperamental at the moment, and there's something about you she's not keen on."

"What does that mean? I'm great!" Ruby laughed.

"I know, I know, but just let her do her thing."

All of a sudden, another alert rang around the console room.

"Oh, that's not good," the Doctor muttered, his trained hands flying across the controls, "what's up, babe?" he asked the TARDIS.

The time machine shook a few times, before falling still, the silence broken only by a soft FWUMP noise.

"That was a close one!" the Doctor joked, looking up to check that Ruby was OK; or at least, he would have done if she was there.

Moving around the console, he saw that where Ruby had been stood only moments before, there was now a pile of clothes; the blonde teen was nowhere to be seen. Now he realised what the sound had been.

"Oh, this definitely isn't good."
