Then there is Marvel’s stealth Agent Carter project. Last year, the company went into Fort Knox mode on its Agents of S.H.I.E.L.D. pilot, which was kept under lock and key. They took that a notch further this year with Agent Carter. Because there is a prototype — the project is inspired by a one shot, which was featured on the Blu-ray release of Iron Man 3 — word has been that it would forgo a pilot and go straight to series. The script was finished more than three months ago (“the script is great,” ABC’s Paul Lee said back in January), the option on one-shot’s star Hayley Atwell came up and was extended, but the green light never came. Now there is talk that a pickup for Agent Carter may come along with a renewal for Marvel’s freshman Agents of S.H.I.E.L.D., with the new series possibly serving as a bridge between the fall and spring portions of S.H.I.E.L.D.

As soon as the west coast feed of "Turn, Turn, Turn" ended last week, you changed your entire Twitter layout to reflect HYDRA, which was just great. You're very active on social media, live-tweeting puns during the show. How long did you have that changeover planned?

I sat with the big information they gave me for a couple of days, and I'd say about a week or two after, I thought, "Man this is a great opportunity. Man, this is great." I remember live-tweeting and thought, "Wouldn't it be cool if we did a fun little Twitter stunt where at the end of the episode, what would happen if we changed everything and then it went black?" Then, all I had to do -- Marvel has the best people. I just mentioned that and Samantha Thomas, a producer on the show, helped me with the whole thing and helped facilitate that.

It was a really cool thing. I've never done a Twitter stunt. I usually just hang out with the puns and I find that quite fun, and it's a relief that others do too! [Laughs] It's nice there are others out there who appreciate that, because when you say those things out loud, people just roll their eyes and ask you to leave the room.

When it actually happened, I was watching and I was seeing all the Tweets come in, and I laughed out loud when everyone said, "What? Oh my God! Nobody saw that coming!" But I was talking earlier about how personal feelings can come into it, a personal reaction could come into something like this. And everybody seemed to feel so betrayed that a lot of it came out as, "I can't believe that you did this! I feel so betrayed and I hate Grant Ward now. [Laughs] If you read enough of those, it's hard not to take those kind of personally. There were people who were just so shocked and believe in Agent Grant Ward so much, and SkyeWard -- they believed in this direction they thought it was going, that they were just outraged when it took a turn. But as it came out as a manifestation, there was a lot of the word "hate" in there, "I hate your profile pic, you have to change that, that's just rubbing salt in the wound!" stuff that came out afterward that I got to experience first hand.
