RL: And after...

[skullfuck_a_nun]

Chloe stayed behind one of the many nooks and crannies on the TARDIS, listening to the familiar 'vworp vworp' noise the time machine made. She had escaped with her life; she was bruised and scratched up, her hair had been torn out of their braids and fell in fiery waves down her back, and her butt was going to kill her in the morning. But she was alive.

But she wasn't done yet.

Ten. Doc.

He wasn't okay. So Chloe wasn't okay either.

So while the good Doctor sent everyone back to their worlds, Chloe stayed behind, hoping to stay hidden till everyone was gone.
