I think it might be “a little late to be part of the fun”

I can’t believe the Doctor just told us we’re from a separate timeline in which we didn’t land on Mars in 2019… What a bunch of amateurs we must look like compared to the other universes. I’d rather not have been made aware of this at all! Now I’ll have to live in shame of the knowledge that we’re the timeline that’s living in the past. Well, thank you for that, Doctor. What a b*tch.
