Johnny Lee Miller was great, really looking foward to having more of his character in the upcoming episodes. I really like where they're going with the possible 'secret brotherhood of serial killers' angle. Luemen and Dexter (or Julia and Michael's really) have very good chemistry. I don't see the relationship getting romantic...and I kinda like that. It's like him taking on a sidekick, a partnership like he said with his final monologue to end the episode.
I thought they made good strides, on all fronts, with the latest episode. Laguerta looks like a sinking ship, because it was her judgement call that got people killed. I'm not even sure who'd they promote, but her days in charge look numbered. I like where the Quinn and Debra thing is going, with Robocop becoming a nice hiccup for Quinn.
I'm curious to see where the Santa Muerte story is headed, now. I still think it could tie into the Jordan Chase thing, somehow. Or maybe they've got nothing to do with eachother.
