After last night's dramatic episode "Scars", the stage is set for Marvel's Agents of S.H.I.E.L.D.'s explosive two-part finale next week, "S.O.S. (1)" and "S.O.S. (2)", both airing on Tuesday, May 12 ABC. In last night's episode (bold|SPOILER WARNING!), Bobbi (Adrianne Palicki) was captured by Agent 33 (Maya Stojan), Gonzales (Edward James Olmos) was killed by the Inhuman Jiaying (Dichen Lachman) and the S.H.I.E.L.D. team has brought Cal (Kyle MacLachlan) into custody, unaware of how dangerous he really is. Today we have a new poster, which teases that Cal will transform into his monstrous alter-ego Mr. Hyde from the comic books. Executive producer Jeffrey Bell also teased how the two-part finale and this week's episode were essentially conceived as a "three-parter."

"Episodes 20, 21 and 22 almost work as a three-parter. I think because we were doing the full two hours on the final night, we really decided to just lead into that. We left episode 20 with Jiaying saying "this is war," and Skye assuming that Gonzales shot her and attacked her, so we have S.H.I.E.L.D. and Inhumans and all our different threads finally coming together. And Skye is really torn between these two factions, between her surrogate family and her real family. Where will she go with that? And we've been promising Inhumans and some fun powered stuff, and hopefully we can make good on that promise as well."

The executive producer also called the two-part finale, "big" and "emotional," with some "twists and turns and surprises." When asked if Jiaying killed Gonazales out of fear of the Inhumans being indexed, or losing Skye to S.H.I.E.L.D., Jeffrey Bell had this to say.

"It's really the bigger picture. What Jiaying says is true. She has set up a community in the middle of nowhere so they would be left alone. We know that her experience in the past with SHIELD - even though we know it was Hydra masked as SHIELD - was horrible. So now here she is with SHIELD showing up at her doorstep saying, "Hi, we don't want to hurt you, but we do want to index you, and we do want to monitor you," and that didn't work well for her. She is trying to protect her people. I don't think she's a bad person for doing it, but the way she's doing it seems a little bit suspect."

The poster for "S.O.S. (1)" will be available for purchase on Friday, May 8 at 12:30 AM PT. The one-sheet will cost $49.99, although there will only be 100 copies sold through MarvelShop.com/AgentsOfShield. Check out the poster below, and come back tomorrow to see the "S.O.S. (2)" artwork.
