3.18 “Exposed”

Sandra discovers that Claire has been hiding Alex, and with her help, Alex evades Željko’s agents and leaves Costa Verde. Sylar and Nuke pull over at an abandoned diner, and we flashback to the day Papa Gray sold Sylar to his aunt and uncle and sliced Mama Gray’s head open. Meanwhile, following a lead from Rebel, Peter and Matt whammy their way into Building 26. They don’t find Daphne, and Matt gets captured, but Peter downloads footage of Nathan’s operation and delivers it to the evening news. Željko retaliates by strapping explosives to Matt’s chest and dropping him off in the middle of D.C.
