Agents of SHIELD left off with a big reveal in December, as we learned that Agent Melinda May has been replaced by an LMD (Life-Model Decoy), while the LMD Aida has captured the real May.

With SHIELD back tonight, I spoke to Ming-Na Wen about this turn of events and what it's like for her to once again find herself playing two different characters, having previously protracted May's doppelgänger Kara Palamas/Agent 33. And whether we could eventually see a May vs. May LMD fight, like we did with May and 33.

I know! It's like, wait a minute, it's more work, right? [Laughs] But I think that as you'll see when these episodes air it's a really fun challenge to play the two characters because unlike the last one where I was able to depict another character very distinctly and different – she was a different person -- this is a replica of May. I think that was a challenge and then it was a challenge to keep track of which one is the LMD, which one is the real May in doing the show and I think it progresses into a lot of reveals about who she is. That's always fun. That's a good, what is it, trick to use.Yeah, I found out when I got the script.Jed [Whedon] jokingly said when I asked him, "So, what happens in the next episode?" He's like, "You die." And then it's true, I died. Sort of, but I did come back, thank goodness.In a strange way, yeah. Without being able to say anything or give anything away, but for me, you have to start thinking a little differently as an actor. Yeah, it's... We'll leave it at that! [Laughs]I would love it. I think it would be fun for the fans because that was such a memorable fight scene and to be able to do it again, it would be great. I say that now, and then I'll regret it if it does happen! The stunts on the show, it is really incredible what we do jam into a day. We were just shooting in Valencia until 1 or 3 in the morning and that's just what we do. It's like, okay, holiday is over. Let's get back to work!It's still great. I mean, I think the fans will be really happy with how this next arc is going to progress because they do get closer... One way or another, right?Yeah, I think it's remarkable how our writers can come up with such varied storylines. It could have been so easy to just do like a CSI thing - one similar story after another with a formula that we go after the bad guys. But this is really more in the genre of the comic books where it's unfolding story after story and layering how these characters interact, fall apart, come back together. About the family, about the mission and just being able to constantly come up with stuff that challenges us all the time. Every episode is so dense and complicated, I don't know how they break it down and make it work. It's remarkable to me because half the time after I read the script I have to re-read it to go, okay, where is everybody? Where all the characters are and how the storyline falls.
