In the stream of pictures, Sophia is also one of them.

Sean has a flash back to a week ago aboard the cruise. Leila encourages Sean to go on the scuba adventure with Vicky. Greg comes to visit and before he starts to get physical, the secret men come in and kill Greg and take Leila hostage.

The time flashes back to 1944 when the spaceship lands in Alaska.  Sophia tells her partner to run and escape before they all get caught.

Back to the present, the President questions Sophia what her true intentions are.  She warns him that he people have been waiting over sixty years to escape and they’re growing impatient.

Sean is trying to escape the hospital when he has a flashback to five years earlier when he meets Leila in a swimming pool.

Blake assigns Agent Lee to the top of their defense agency. Ten years earlier it flashes back to when Lee is getting administered blood work. Agent Lee is one of the aliens that infiltrated the CIA.

Later Lee meets with Thomas who tells him where he can find the plane, but they are still using the people.  Lee gets to the crash and finds Michael and all the people on the plane dead.
