Here’s the trailer of “Us or Them”, the next episode of The Event:

The Event S1x19 Us or Them
“While Sterling and Chief of Staff Peel try to identify the traitor within the White House, Sophia continues her campaign. Meanwhile, Leila and Michael rescue Simon, and Sean and Vicky try to track down the courier transporting the sleeper weapon.”

I wish Sean would ditch Leila for Vicky!
