This makes up for the rest of the season. I thought about what would happen if Deb walked into the Church, thinking that Dexter is doing his work in order to talk to him some more or tell him about her feelings. I don't know what's going to happen next season. I imagine at least Deb will reveal that she's had suspicions that this is what Dexter's been up to.
This could potentially make for a great 7th season.
