Six and Seven! I ended up putting the two pandas together to show to someone, and I think they look like a great double act. Of course they never actually meet in the show, but in Big Finish their paths do cross, and it is fabulous. Their interactions are especially fun with River in The Diary of River Song 2, with a smitten Six and a scheming Seven working with (and against!) her.

Would you want to cross paths with these two?
