“One Of Us” is episode thirteen of season two of Marvel’s Agents of S.H.I.E.L.D.
With Skye’s abilities being revealed in the previous episode, “Who You Really Are”, she is going to be put on the Index. May gets her ex-husband to come and do a psychiatric examination of Skye.
Skye’s father, meanwhile, is recruiting a few people on the Index to help him in his quest against Coulson and S.H.I.E.L.D. He believes S.H.I.E.L.D. to be monsters, and hasn’t forgiven Coulson for killing Whitehall in “What They Become”. Not that he liked Whitehall at all; he just wanted to be the one who killed him. Sort of unbalanced logic there, but he’s an unbalanced man. Consequently, the place he is going to make his point is Coulson’s home town. Skye’s father also reveals that he has chemical enhancements with unfortunate side effects.
Mack has taken Hunter away after incapacitating him at the end of the previous episode. In this episode Mack reveals who he and Bobbi are working for.
