doctor who and the t.a.r.d.i.s

So my Professor was talking about how phone booths are obsolete technology that nobody has use for anymore and I KID YOU NOT the sixty-something, super serious Business Mathematics instructor popped his head in the door and yelled, “DOCTOR WHO HAS A PHONE BOX!” And on his entire trip back down the hall you could hear him shouting, “Gallifrey falls no more!”
Day. Made.


So I honestly 100% believe Ms. Frizzle is actually River Song, I mean just look at her, her antics, her mug shot and her hair is close to similar. Honestly? a time traveling, space traveling school bus….more like River stole another T.A.R.D.I.S. with a functioning chameleon circuit.

Capaldi has said, “the 14th Doctor is someone we’ve seen on the show before.”
Both Capaldi & Moffat teased 13’s “regeneration” in Lie of the Land.
Why have 2 ‘Masters’ in one season, at the same time?
Both Capaldi & Moffat have said on several occasions that this regeneration would be unlike anything seen before…
The 13th Doctor 'realised’ he’d seen his face before, and it was finally revealed that Time Lords CAN choose their face to help them remember certain things.
What, or WHO, could fit all the clues laid down by Moffat & cast?
