Quick recap
Kelly holds Zach and wants the Occido Lumen in exchange for the boy. Fet fights the strigoi alongside Navy SEALs, and Eph works on a bioweapon against them. Palmer, dying, bargains with Setrakian for the white essence. A nuclear bomb smuggled from Russia turns up aboard the Aurora Cutlass. In the end, the Master ambushes Palmer and takes his body. The team traps the Master in a silver-lined sarcophagus. Kelly attacks Eph, who kills her in self-defense. Enraged, Zach sets off the bomb. The Master breaks free, fallout blocks the sun and the strigoi can now walk in daylight. Eichhorst takes Zach, and Eph heads into the chaos to find him.
