Rule number one: Moffat lies.
Accurate portrayal of Moffat: "I'm not bringing the Master back. Oops, goodness me, did I say that out loud? Oh golly gosh, I guess I've accidentally told you the truth now".
But it's one thing to tell a lie like that to surprise people, and another to create expectation for something you don't plan to do? That doesn't really make sense.

I realized they forgot to address this last night after watching...maybe next season?
I guess that must be it! Next season, or the one after that, you know Moffat. He did say that they'd play that one out over time. Which, coupled with Capaldi's comments (which tbf may have been playful, I haven't seen the context), makes me worry that it won't be something straightforward.

well tbf he could pick that one up later on in S9 or whatever. I'm also not sure how much those interview bits were supposed to be a confirmation that he was actually including this plot. after all RTD's old idea doesn't really fit anyway imho
It wasn't just from interviews from when Capaldi was first cast, he has reiterated it since, and it sound like he means business. It sounds like he wants to answer the question of where the Doctor's faces come from. My theory to incorporate RTD's idea is that it's a reminder to the Doctor that he's on borrowed time (the extra lives given to him by the Time Lords, the extra life the Doctor gave Caecilius) and his comeuppance will come (like it did for Frobisher, but that can be left unsaid because kid's show). It's not a theory I'm particularly fond of, but it's an example of how what RTD said could be used.
Thank you for the replies!
