Spoiler:
I have been wondering whether Deb set Hannah up, i.e., poisoned herself. Seems like some others share that thought, so maybe that was her play. It would fit with Dex letting his guard down on the Laguerta/colombian dude set up as well. And Deb is a wacky enough character that I think the writers could make us believe she'd do it, especially after she says "its because I love Dexter that I will do whatever, blah blah" the night before the accident.
