The second half of Doctor Who Season 7 will kick off on March 30.

What can fans expect from new spring episodes on BBC America? A focus on Jenna-Louise Coleman's Clara, that's made clear in the following promo, as the Doctor says to his new companion:

Coleman made her unexpected debut in the Season 7 premiere, "Asylum of the Daleks," coming on board as a space traveler named Oswin Oswald. She then returned as Clara for Christmas.

So we've met Clara twice. And yet sort of not at all. Watch the Doctor grow especially confused by this companion now:
