Time for the second of the three "Doctor Whovideo interviews I conducted at Comic-Con, this time with co-star Karen Gillan.

This is the second time I've interviewed Gillan in the last few months, and while it's considerably shorter than our conversation in New York, there were certain topics we could discuss here that we couldn't in the spring - notably how Gillan and Matt Smith found out about River Song's big secret, and how they reacted to it.

We also discussed what it was like for her and Smith to walk the Comic-Con floor and be treated like rock stars, and more.

Smith coming up later today.
