Mockingbird in "A Fractured House", airing Tuesday, October 28 at 9 PM ET on ABC. To promote tomorrow night's episode, Adrianne Palicki has debuted a special video message, where she is seen wearing her full Mockingbird suit, as the actress reveals she will be live-tweeting the episode with Clark Gregg.

ABC has also debuted a new photo of Adrianne Palicki in her full Mockingbird attire, along with a new promo from the episode, which reminds fans that we will get an exclusive scene from Avengers: Age of Ultron at the end of "A Fractured House".
