Anya takes over when Sparks begins to question the mission and Molly find out about Yasumoto's painful path to immortality. 

Molly continues to search for her offspring while Yasumoto holds her family as hostage to get him. So he thinks. Instead John turns the tide when, after sending Ethan home, he gets the last vial of the serum that keeps Yasumoto alive.

Yodin messes with Ethan, but we don't know in what way.

Yasumoto shares with Molly how he got the serum.

Spark's ex-wife is dead and the offspring is taking a hike.
