Morgana looks up at herself on the screen and is immediately taken aback. Under any other circumstances, she probably would have waved just to prove that it really is her, at this moment (being projected on anything, is a surreal experience for someone of her time).

While the Doctor has figured out that they are being watched -- something Morgana is tired of -- her last 6 months have been spent under close scrutiny, the skeletons have not stopped advancing.

Even the headless one keeps moving. They've already made it halfway across the room.

So, never let it be said Morgana does not acknowledge when she is wrong. "Doctor, do you remember what you said earlier, about running?"
