Entertainment Weekly has revealed the latest in the line of episode-centric posters produced for the back half of "Marvel's Agents of S.H.I.E.L.D.'s" second season. The latest image, tied to next week's episode "One Door Closes," focuses on Adrianne Palicki's Mockingbird.

Whereas previous posters have come from artists with Marvel history like Gabriele Dell'Otto, Marcos Martin, Declan Shalvey, Jordie Bellaire and Annie Wu, this week's piece of art comes from Chicago's Delicious Design League. The EW article states that the League was founded in 2006 by Jason Teegarden-Downs and Billy Baumann and has provided illustrations for Twitter, Firefox, HBO and more.

The upcoming episode will focus on Palicki's S.H.I.E.L.D. agent and her relationship with Edward James Olmos' Gonzalez as well as reveal what she and Mack have been up to all season long.

"We've worked hard to sort of set that [theme of 'who you really are'] up at the beginning of the season and to run with it, and now that we're nearing the end, we're still running with it -- hopefully in fresh ways," said "S.H.I.E.L.D." executive producer Jeffrey Bell in the reveal interview. "And so right now, what's fun is, 'oh, HYDRA isn't so much the antagonist as much as another faction of S.H.I.E.L.D. seems to be the new antagonist.' And when you're doing 22 episodes, you do have to make those kinds of moves to keep the audience interested."

With her double S.H.I.E.L.D. agent identity exposed, Bell also discussed whether or not Bobbi Morse has more secrets to spill.

"I hope she has other secrets, or we're out of stories! [laughs] This is the big pressing secret she's had, but clearly, she and Hunter have been keeping secrets from one another, evidently for years. And one of the things I find interesting about her is she seems to be more of an ideologue -- she's loyal to an idea -- and sometimes, the short term of what appears to be betrayal or short term conflict is often because of what she views as the greater good. And that's an interesting character to have in a world where Coulson is much more 'we need to protect or save that person.' Are you loyal to a person? Are you loyal to the guy in the bunker next to you? Or are you loyal to the larger concept of what we're fighting for? And having her represent that, I think, has generated a lot of interesting discussion and story."

"One Door Closes" airs on ABC on March 24.
