From the BBC:
Former 'Emmerdale' actress Jenna-Louise Coleman has landed the role of the Time Lord's new companion in 'Doctor Who', the BBC has confirmed.
Producer Steven Moffat announced the actress will replace Karen Gillan's character Amy Pond when she leaves the show in the next series.
Other credits for Coleman include the four part mini-series 'Titanic', which was scripted by the creator of 'Downton Abbey', Julian Fellowes. She'll be making her first appearance in the 'Doctor Who' Christmas special.
I found this quote by Moffat interesting and one to stir the televisiological pozz'bilities in what passes for my brain:
"Who she's playing, how the Doctor meets her, and even where he finds her, are all part of one of the biggest mysteries the Time Lord ever encounters. Even by the Doctor's standards, this isn't your usual boy meets girl."
And in the BBC press release, they mentioned that the Doctor and Coleman's companion will meet in a "dramatic turn of events as the show builds towards its enormous, climactic 50th anniversary year".
Of course, isn't everything of import on 'Doctor Who' a dramatic turn of events?
But here's what I'm thinking.....
What if Jenna-Louise Coleman's character turns out to be a link to the Doctor's Past, and by "Past", I mean that she serves as a bridge to the old series for 'Doctor Who'.
What if she is somehow related to someone who once travelled with the Doctor? (I wouldn't want her to be that character from an earlier Incarnation's adventures. Then we would have to deal with the recastaway problem.)
And I have that someone in mind.....
What if it turned out that Coleman's character is the daughter of Zoe Heriot?
Because Zoe's memory has been wiped clean of her time with the Doctor, there wouldn't be any residual baggage to deal with - at least, not until the show wanted to bring Wendy Paddington back in the fold for an episode or two. (In much the same way that Sarah Jane Smith returned to the show.)
It's my suggestion only. But it certainly would fulfill all those hints in Moffat's statement:
"Who she's playing, how the Doctor meets her, and even where he finds her"
Zoe's daughter, during an adventure in the Future, and on board the "Wheel in Space".....
I know it's a long-shot, but it would be a fitting connection to the old series as we head into the celebration of the 50th anniversary!
