Dexter is checking out what look like abandoned large waterfront sheds (hope you know how to cover your search history, Dex) when he gets a text from Hannah. Cut to the two of them hauling a large tree into her house, during which Hannah asks Dexter if he's still doing Christmas Day with Deb and Harrison, like that's the kind of plan that just casually falls apart. Dexter's like, you could join us; but while Hannah is a killer, she has a bit more social sense than her boyfriend and as such is like, that would be an actual historical disaster? Inside, Dexter suggests they start a new tradition of celebrating on Christmas Eve and Hannah thinks that sounds good -- except she hasn't gotten Dexter a Christmas present yet. Aw, that's nice, Hannah. Just nothing ingestible, please. They put their arms around each other and regard the tree beatifically...
...and then it's night and Deb -- in her car staking out LaGuerta's house -- pops an anti-anxiety pill and washes it down with some bottled water. She then sees LaGuerta emerge and drive away, and once Deb judges that she's safely gone, she gets out, and... steals the star off LaGuerta's tree? We cut away, so we'll never know.
Speaking of stakeouts, Dexter is sitting by the prison entrance when he sees Estrada emerge and a look at his chasing after a nearby bus is all that's needed to convince Dexter his death-dealing services won't be, if you'll forgive me, overkill in this case.
Oh, Quinn comes into the strip club and talks to a dancing Russian stripper who was apparently a friend of Nadia and who tells him she left for Vegas, as she needed a fresh start. The dancer adds that Nadia was really broken up and that she'll never forget what Quinn did for her. Quinn winces at how stupid he is, catching up with the rest of us.
