Hints posted on combom from "The Girl Who Waited". I didn't bother with spoilers because it's ridiculously cryptic.
Doctor Who's Tom MacRae Hints at Series 6 Episode "The Girl Who Waited"
In celebration of a swift 2000 followers on Twitter, Doctor Who scriptwriter Tom MacRae promised and delivered three quotes from his episode "The Girl Who Waited".
"How can you have a door without a wall?"
"The Green Anchor…The Red Waterfall."
"You want to update Twitter!?"
Start speculating, everyone!
MacRae, who previously wrote "The Age of Steel", went on to debunk one prevalent rumour about his Series 6 script.

My ep was NEVER called ‘The Green Anchor’, but the Green Anchor is very, VERY important! And also the best place to be.
Then he decided to be even more cryptic.
Amy’s favourite cat was called Biggles. What’s important is – that’s the name she DIDN’T use later on..
"The Girl Who Waited" is Episode 10 of Series 6. Some reporting from this post came from Doctor Who TV.
