“Marvel’s Agents Of S.H.I.E.L.D.” Season 2, episode 5 will continue to show the inner workings of Hydra. In episode 4, Hydra agents discovered that Phil Coulson (Clark Gregg) is running S.H.I.E.L.D., and that could mean the agency will target him. However, it looks like Hydra will be busy turning good agents bad. Bobbi Morse (Adrianna Palicki), a.k.a. Mockingbird, will make her first appearance in “Marvel’s Agents Of S.H.I.E.L.D.” Season 2, episode 5, but it doesn’t seem like she's working for S.H.I.E.L.D. -- they lost her to Hydra.

Simmons (Elizabeth Henstridge) is still successfully undercover in Hydra’s labs. Bakshi (Simon Kassianides) seems to trust her since she saved his life. However, things will take a turn for her when Hydra’s Security Chief Bobbi Morse reveals that they have a mole inside Hydra. The promo shows Simmons running, but it isn’t clear if her cover has been compromised. If she's discovered to be working for Coulson and S.H.I.E.L.D., Hydra could kill her or brainwash her. The episode 5 promo indicates that Raina is somehow in control of her future.

Watch the promo below:

Hydra also seemed to take control of Raina (Ruth Negga) in Season 2, episode 4. It appears that she gave the obelisk to Whitehall (Reed Diamond) within 48 hours because she's alive and well. Now it’s Skye’s father (Kyle MacLachlan) who's forcing her to give him something. The Doctor is done waiting to see Skye (Chloe Bennet). He wants to see her now, and he doesn’t care about the consequences.

“Marvel’s Agents Of S.H.I.E.L.D.” Season 2, episode 5 will air Tuesday, Oct. 21, at 9 p.m. EDT on ABC. Do you think Simmons’ cover will be blown or will she be able to convincingly lie? Sound off in the comments section below!
