Doctor Who - The Glimpse (or: Time Crash, in the '60's)

[Emperor-Tiberius]

Cushing reference? I thought that was a War Doctor reference.

 

[Ithekro]

It was both. Two and Eleven mention the one with the mustache, but Nine say he's over here. "Oh, than here's another we don't talk about" Meaning there are two with mustaches present at the table. Both the War Doctor and the Cushing Doctor.
