Ever since Marvel's Agents of S.H.I.E.L.D. returned with the back half of Season 2, Entertainment Weekly has been debuting a new poster for every new episode. Today, we have the one-sheet for "One Door Closes", airing Tuesday, March 31, featuring none other than Adrianne Palicki's Bobbi Morse, a.k.a. Mockingbird, designed by Chicago artists Delicious Design League. Executive producer Jeffrey Bell also teased new details about "One Door Closes", which will give fans more insight into Bobbi and Mack (Henry Simmons).

"We're finally explaining 'Oh, this is why Bobbi and Mack feel the way they do about this whole thing.' I think we really earn their story. It shows you what they've been going through is well-earned, and that will all be revealed next week."

The last episode, "Love in the Time of Hydra", introduced fans to Edward James Olmos' Robert Gonazales. This coming episode will explore Bobbi's history with Gonzales. When asked how Gonzales helped "shape" Bobbi into who she is today, Jeffrey Bell had this to say.

"I don't know if it's so much how Gonzales shaped her so much as who Bobbi might really be. She came in here having been undercover at HYDRA and then we reveal she has this secret agenda, so in many ways, as a spy, you keep going "who is she, really?" And I think in 15, you'll get the clearest sense of this is who she is-this is what she believes in, this is why she does the things she does. And Gonzales is a piece of it, but she comes in with a very clear singular vision of what things are. And there's a moment in 15 that really defines the direction of her and Gonzales and Mack and a lot of people, that pivots off of her. So I think more than anything, you'll get a sense of who she is at her core, which I think people will like."

The art for "One Door Closes" will be available for purchase Friday, March 27 at MarvelShop.com/AgentsOfSHILELD for $49.99 (limited to 100 copies) at 12:30 a.m. PT.
