The BBC have released the trailer for Doctor Who Series 9! It's already set me (and countless other fans) off on wild flights of fancy, trying to figure out what the series has in store for us. The biggest question posed by the trailer is, just who is Maisie Williams playing? The Doctor seems to know her and she seems to know him. They seem to have not seen each other for some time ("What took you so long, old man?"). Could this be The Doctor's granddaughter, Susan?
If this is the case, this is pretty huge!
As we saw in The Name of the Doctor (2013) Susan escaped from Gallifrey with her grandfather, The Doctor back when he first nicked his TARDIS. She was with him right at the start! Apart from The Name of The Doctor (where we only see the back of her head) she hasn't been seen properly in the TV series since she was abandoned by The First Doctor in future London following The Dalek Invasion of Earth (1964). Well, technically she turned up in The Five Doctors during the '80s, but she didn't really do much except fall over for no reason, so that doesn't count.
There was one blink-and-you'll-miss-it moment in the trailer that backs up the theory that Maisie Williams is Susan. If you look carefully during the trailer you can glimpse a grey Dalek with smaller lights on it's head...
The Dalek is blurry but what we can see of him looks very much like the Daleks seen in Dalek Invasion of Earth, Susan's last appearance!How carefully did you watch the Series 9 trailer tonight? SPOILERS!!! pic.twitter.com/cxP8CciXQ6— Jon & Gav (@Dalek6388) July 9, 2015
Am I right? Probably not. After all, my Missy theory was way off. But it's fun to speculate. Can't wait for the 19th of September!
