Bobbi Morse, a.k.a. Mockingbird (Adrianne Palicki) goes on the hunt for a Hydra mole in a new clip from next week's episode of Marvel's Agents of S.H.I.E.L.D., "A Hen in the Wolf House", airing Tuesday, October 21 at 9 PM ET on ABC.

We reported in August that Adrianne Palicki joined the cast as Bobbi Morse, with fans getting their first look at the character last month. We won't get to see Bobbi transform into Mockingbird right away though, since, as you can see in this clip, she is introduced as the head of Hydra security, who announces there is a mole in their midst, as Simmons (Elizabeth Henstridge) nervously tries to keep her composure. It isn't known exactly how many episodes the actress has signed on for, but her Mockingbird nickname was teased in the Comic-Con footage.

In the Marvel comics, Bobbi Morse was injected with an experimental serum that gave her superhuman strength and speed. She eventually became a S.H.I.E.L.D. agent and then one of the Avengers, and was romantically involved with Clint Barton, a.k.a. Hawkeye. It remains to be seen how faithful this version of Mockingbird will be to the comics, but you can take a look at this character in action below with this new clip.
