Paul Lee, ABC's entertainment president, took some time at the Television Critics Association's winter press tour to field questions about Marvel's Agents of S.H.I.E.L.D., including the show's ratings and the previously announced appearance of Jaimie Alexander's Lady Sif in an upcoming episode.

"It was obviously disappointing that we started with a very high number and it came down," he said. "It took a little bit of time to find our sea legs, but now the show is really doing well. Creatively, we are loving what we’re seeing for the back nine. We’re doing a lot of work, and I’m really enjoying doing this with Marvel. We can announce that Lady Sif is coming in, in Episode 15. We’re shooting it now, and that’s going to be absolutely integral to that hour of television. And then, there’s going to be this really cool arc to the end of the season. You’re going to find out who the Clairvoyant is, and it’s going to be very, very cool."

Lee went on to discuss some of the stumbling blocks the series hit in the first half of the season. "It did take us a little bit of time to find our sea legs," Lee said. "I think the key to us was really starting to work closely with the studios, and really figure out with our showrunners and all the creative brains, how we could have a show that didn’t have Iron Man in it, but did have an incredible amount of the Marvel universe and an incredible amount of the mythology that went through there. We also took a little bit of time to get the balance between a procedural and an arc. I’m so proud of how they’ve now arced out the last nine episodes. But, that’s something that many shows do, as they go through that."

Marvel's Agents of S.H.I.E.L.D. airs Tuesdays at 8 p.m. ET/PT on ABC.
