Complete story — includes the ending
Kat threatens to walk out on everything, while Bill is the only one who can get through to her. Dr. Rosen is healed as much as possible by another Alpha. Dani returns in what appears to be Dr. Rosen's hallucinations. The team races against time, learning Parish has set the photic stimulators to go off at 8:18 p.m. on the 150th anniversary of the day he discovered he was an Alpha. Gary visits his mother in the hospital, where he runs into Dr. Rosen. He helps him find Parish's "god's eye view", in Grand Central Station in New York City, where Parish plans on watching the "end of the world". The team races to find and disable Parish's bombs, while Dr. Rosen and Parish square off. When the photic stimulators go off in Grand Central, Gary is the only one not affected.
