Change is the one constant in the Doctor Who universe. The Time Lord is getting a new traveling companion. Amy (Karen Gillan) and Rory (Arthur Darvall) are leaving the show. Jenna Louise Coleman will join Matt Smith next season. Coleman played Connie in Captain America: The First Avenger.
“She’s funny and clever and exactly mad enough to step on board the TARDIS. It’s not often the Doctor meets someone who can talk even faster than he does, but it’s about to happen. Jenna is going to lead him his merriest dance yet. And that’s all you’re getting for now. 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,” Executive Producer Steven Moffatt told Spinoff Online.
