Marvel's hit series 'Agents of S.H.I.E.L.D.' returned with Episode 5, entitled "A Hen in the Wolf House," with shocking revelations and new characters to look forward to, while Episode 6- "A Fractured House" will further aggravate the tension between S.H.I.E.L.D. and Hydra.

Season 2 of 'Marvel's Agents of S.H.I.E.L.D. has seen some new characters already, including Sunil Bakshi (Simon Kassianides), Peggy Carter, and Lance Hunter (Nick Blood).

Episode 5 will show Phil Coulson (Clark Gregg) along with crime-busting agents facing a new enemy, while another agent is on the verge of being exposed as a private detective.

Last week's episode saw Jemma Simmons (Elizabeth Henstridge) as an undercover agent at Hydra. Hydra agents found out that Coulson is the operating S.H.I.E.L.D. which means that Hydra will target him.

Phil and May Coulston, on the other hand, worked on a special undercover mission to find the painting with a mysterious text that might be able to answer their questions and clear the up confusion.

Meanwhile, ABC released an official synopsis of Episode 5 revealing that undercover agent Simmons will come face to face with the powerful and authoritative Security Chief for Hydra-Bobbi Morse (Adrienne Palicki), or more popularly known as Mockingbird's alter ego.

Morse believes that a traitor is in Hydra, and attempts to stop that traitor in any way possible, while Phil Couslon and his team in S.H.I.E.L.D. will try to stop the compelling Security Chief.

Fans will also see Agent Skye's (Chloe Bennet) backstory as her father convinces Raina to help him reunite with his daughter.

Meanwhile, next week's episode titled "A Fractured House" will show Hydra trying to impersonate S.H.I.E.L.D. so they will be attacked by The United Nations. On top of that, S.H.I.E.L.D. will also be faced with an "unexpected enemy that will bring about their downfall."

Episode 5 of 'Marvel's Agents of S.H.I.E.L.D.' premiered on Oct. 20 while Episode 6 "A Fractured House" airs on 9 pm Oct. 28 on ABC Television Network
