Julie finds out a dark secret about Odin while Molly finally comes face to face with the offspring. 

Odin's true nature comes to light although not much about his plan for Ethan.

Katie Sparks isn't Katie Sparks. She's been rotting on the Seraphim.

Fake Katie puts Glass into the cell with Dead Katie and tells him it's okay.

Molly connects long enough with her other son for him to tell her she's the only one who can stop the bloodless ones from coming to earth.
