Plot summary
Cal recruits dangerous individuals from S.H.I.E.L.D.'s Gifted Index to settle his vendetta. Coulson and Morse investigate and are led to the former's hometown of Manitowoc, Wisconsin, where the criminals have seized the local school stadium. May enlists Dr. Andrew Garner, her ex-husband and a psychoanalyst, to work with Skye, who is now on the Index herself. During one of Garner's talks with Skye, Coulson requests back-up, prompting May to fly the Bus to Manitowoc with Garner and Skye on board. At the stadium, Coulson is confronted by Cal, while May arrives, bluffing that she will kill Skye.
During the stand-off, Gordon appears and teleports away with Cal. As Coulson's team subdues Cal's group, Skye starts causing tremors, only stopping this by directing her abilities inward, resulting in hairline fractures throughout her body. Elsewhere, Mack hides Hunter in a safe house until they are extracted by an organization that Mack calls "the real S.H.I.E.L.D.", and Gordon takes Cal to his superiors, belittling him for using science to increase his strength.
