Yay. Mark Gatiss had two good episodes in 7a, didn't he?
Gatiss didn't write anything in 7A. 7A consisted of:
Asylum of the Daleks by Steven Moffat
Dinosaurs on a Spaceship by Chris Chibnall
A Town Called Mercy by Toby Whithouse
The Power of Three by Chirs Chibnall
The Angels Take Manhattan by Steven Moffat
