Complete story — includes the ending
Dexter attempts to stay ahead of Miami Metro Homicide on his hunt for Gellar, who plans on killing a radical atheist professor, but Dexter fails to stop him after he gets trapped in an elevator. Batista helps Quinn recover his gun that he left in the car of a one-night stand. Dexter later discovers the frozen corpse of Professor Gellar in a freezer in the abandoned church basement and realizes Travis was the sole killer all along; the Professor Gellar that Travis interacted with is actually his dark passenger. Jamie and Louis take a step further in their relationship. LaGuerta meets with Chief Matthews to tell him Debra won't back off on investigating who was with the call girl who overdosed.
