'Agents of S.H.I.E.L.D.' season 4 episode 11 spoilers: Aida makes her next move; Patton Oswalt to return as Koenig brothers

Agent May's (Ming-Na Wen) secret destroys the team on the upcoming episode of ABC's "Agents of S.H.I.E.L.D."

Titled "Wake Up," next week's episode will see the team crumble because of Agent May's secret. According to the official synopsis, May races against the clock to figure out what really happened to her when she was abducted. Meanwhile, Aida (Mallory Jansen) makes her next move, and her deadly plan could mean the end of them all.

On another note, it was recently announced that a familiar face will be heading back to the show later this month. Actor-comedian Patton Oswalt is set to reprise his role as Koenig brothers Sam and Billy in an upcoming episode of "Agents of S.H.I.E.L.D." Titled "Hot Potato Soup," Oswalt's episode, airing on Jan. 31, will see Sam and Billy being tracked down in a bet to get to the Darkhold. Only Coulson (Clark Gregg) and his team could save them, but fans may also see the story bring up a lot of shocking revelations.

Executive producers Jed Whedon and Maurissa Tancharoen recently caught up with Entertainment Weekly, and they shared some teasers on the Koenigs' return. "Patton Oswalt returns as the Koenigs, and we finally reveal their family secret," the EPs said.

Back in season 1, Oswalt made his first appearance as Eric Koenig, an agent from S.H.I.E.L.D. who was stationed at a secret headquarters. The superhero drama eventually introduced his brother Billy Koenig, who was working in a different top-secret base, as well as Sam Koenig, who is behind the Theta Protocol which provided the 11th hour save in "Avengers: Age of Ultron." Sam and Billy are the only surviving Koenig brothers as Eric was previously killed by Grant Ward (Brett Dalton), a Hydra sleeper agent.

The fourth season of "Agents of S.H.I.E.L.D." airs every Tuesday night at 10 p.m. ET on ABC.
