The current season of Agents of S.H.I.E.L.D. is the show's sixth, and it was recently announced that it would be the series' last. This has led many fans to wonder if original cast member Adrianne Palicki, who played Bobbi Morse/Mockingbird, will make a return appearance in the final season.
At this time, there is no word on whether or not Palicki will appear in the final season of Agents of S.H.I.E.L.D.. However, given her close relationship with the show's creators and her iconic status as a founding member of the team, it seems likely that she will at least make a cameo appearance before the series comes to an end.
