Not so much a teaser, more a pair of taunts for the upcoming 50th anniversary story — but there’s also a new scene to see.
The weekend was good for new Doctor Who content if you’re a fan… sort of. New teasers!
I’d class that as taunting Doctor Who fans, really. Although clearly, I want more, so they worked.
In the slightly longer Gods-Of-Ragnarok-We-Want-More class, there’s this bonus scene, not written by Steven Moffat, but instead by Neil Gaiman; originally for The Doctor’s Wife, but now a series 7 boxset minisode.
