"The Walking Dead" webisode actress Lilli Birdsell has joined the cast of "Agents of S.H.I.E.L.D." This news comes on the heels of the Comic-con panel, which confirmed the rumor that Ghost Rider would be debuting in season four.

Birdsell will play a recurring character named Lucy who is described as a haunting character. According to Deadline, Lucy will have a violent side because of her past. No other details have been revealed about her role, but it's possible she could have a connection to Robbie Reyes, "S.H.I.E.L.D.'s" new Ghost Rider.

Birdsell is joining "S.H.I.E.L.D." at a time of great transition for the show. Not only is it moving to the 10 p.m. time slot, but the team is dealing with the loss of Lincoln, the final fall of Hive and Hydra, and the disappearance of Daisy (Chloe Bennet), not to mention a yet-to-be-named new Director of S.H.I.E.L.D.

"Agents of S.H.I.E.L.D." returns this fall on ABC.
