The latest Doctor Who dropped some pretty ominous warnings on the Doctor, Bill, and Nardole -- portents of an imminent invasion, a perplexing ancient text killing its readers, and yes, even an answer to the season-long mystery of just who is inside the mysterious vault. Let us know what you thought of it all in our weekly thread!
"Extremis" gave us at least one major advancement in the ongoing mystery of this season: to the surprise of very few at this point, Missy was the one hidden in the vault all this time. But even with that revelation, we still have tons of questions about just what the hell she did to deserve a thousand years' worth of confinement. Why it was meant to cost her her life, and why did the Doctor choose to let her live? We know there are more Master shenanigans on the way later this season with John Simm's return, so presumably we'll be finding out more about Missy's latest predicament at a later date.
Unfortunately, it really didn't give us much else other than a cliffhanger of an alien invasion for the team to deal with in next week's episode. The mysterious priests searching for the Veritas will be back, and maybe we'll get some actual answers next week, but otherwise "Extremis" didn't really give us much beyond Steven Moffat's beloved twist reveal (it's all a simulation, gasp!) and some very fun moments between Bill and Nardole, who make a great team together.
We'll have more to say in our recap, but for now, share your thoughts in the comments below.
