Watch The Event: Season 1, Episode 17

"Cut Off the Head"

Sophia sends some of her people to other parts of the globe to locate pieces of a weapon she would need in her plans. President Martinez becomes suspicious of his wife's refusal to take the DNA test. Vice President Jarvis meets Sophia with a proposition that could make him President, in exchange of having more of her people arrive to Earth. Sean rescues Vicky and is confronted by Dempsey, who explains that he represents an ancient group, dedicated to protecting humanity from outsiders. He explains what's to come and that he believes that Sean is the one capable of stopping Sophia and her people. Sean refuses, telling Dempsey that his only goal will be to stop him and make him pay for his crimes. Dempsey approvingly agrees, but tells Sean that he will have to make sure that Sean refocuses his attention on Sophia. He then takes a pistol and commits suicide with a shot to his own head, leaving the shocked Sean with a bag containing the information Dempsey says he'll need in his quest. Leila manages to contact Sean using a stolen cell phone and informs him of Sophia's plan.
