Whew, Rose pretending to be the Moment pretending to be Bad Wolf is a mouthful and I love it lolol. I saw lots of theories that she was dressed for a wedding and it went to pieces (poor Tentoo if that's the case, but now Moffat can't sabotage them anymore, soo--). Those are all amazing plots. How to choose. D: They do make sense in the perfect way DW never makes sense but also does make sense #doctorspeak.
Fact.
What if like, it's pre-End of Time, post Water of Mars, when he's at his most volatile, that TARDIS!BadWolf!Moment-whichevah Rose turns up, as it's when he needs her most (lbr) and they can try to figure out her mystery?
