"I have been," Peggy agrees, no mirth or humour in her voice because it's been a very long set of months without any promise of going home, no matter how much she investigates, seeks, explores, she always comes back here and finds herself without a way out or the people that she misses. She's made friends, of course, but they're no substitute for what she has back home.

"You won't find a way back through the fountain. It's solid, I'm not even sure why we come out of that thing."
