Freema Agyeman is the new companion
(And…a new comm already, look! lifeonmartha)
Personally, I liked her in Army Of Ghosts (I have no idea how on earth they’ll get it to work with that, though- is Martha the alt-verse Adi?) and I actually thought it was a pity she wasn’t going to show up again. And now she is. Yay. :D
Not sure I like the name Martha, though. But if that is indeed her name, I hope episode 1 of Series 3 is called Martha, just for balance. ;)
A disturbing thought: this means The Sun was right. :0
