2. Dexter Running Off With Hannah And Harrison
Dexter is head over heels in love with Hannah. He hasn't truly felt this way about anyone since Rita's death back in season 4. Even with Lumen he didn't love her like he loves Hannah. She is completely okay with his lifestyle, since she has it too in a way, and would drop everything and run off with him and Harrison as soon as possible. In the previous episode they talked about running off together, so they could get into some shenanigans up until the series finale where we could see Dexter say an emotional goodbye to Deb and run off with them.
