Jenna-Louise Coleman, Doctor Who's latest companion, made her US talk show debut last night on The Late Late Show with Craig Ferguson, who deemed the actress "the sauciest of all the Doctor's companions." She's got "a bit more moxie," explained Craig, an avid Whovian himself.

The second installment of season seven begins Saturday, March 30 at 8 p.m. ET on BBC America. Doctor Who, new companion Clara and all, returns to television just one day before the premiere of Game of Thrones's third season, which stars Jenna's main squeeze Richard Madden (geek match made in heaven, much?) who plays the ambitious Robb Stark on the HBO fantasy drama.

We can't wait to watch Doctor Who's latest adventures with Clara. What do you think of the new companion, Whovians?
