5. A Hen in the Wolf House

Complete story — includes the ending

Raina begs Skye's father to give her the Obelisk, but he angrily berates her for not delivering Skye, then kills two men for whom he was performing surgery. Raina discovers Simmons' cover and attempts to blackmail Coulson: she will not reveal Simmons to Hydra if she can take Skye to her father. Coulson refuses the offer and Simmons' identity is exposed, though Hydra security chief Bobbi Morse, another undercover S.H.I.E.L.D. agent, rescues her. Coulson has Raina tagged so she can lead them to Hydra; while being surveilled, she also discloses the location of Skye's father. At his abandoned hideout, the team finds the bodies of the men he murdered and he realizes, watching through hidden cameras, that Skye thinks he is a monster. Coulson later shows Skye alien symbols he has been compulsively carving and she believes they are a map. Fitz and Simmons are reunited while Morse, who is Hunter's ex-wife, joins the team. Skye's father delivers the Obelisk to Whitehall himself and offers to join forces with Hydra.
