I finally got around to watching the show where I left off. I have to say that it did get a little better after episode 4 (not 5 like I previously thought), I liked how they portrayed Jordan Chase. "Tick. tick, tick, that's the sound of your life ticking away".. That scene where he walked up to Dexter for a swab was especially nice, kinda reminiscent of how Trinity walked up to Dexter ("hello, Dexter Morgan") in the 4th season, likewise with the phone call to Lumen, that was good. I went in the last episode thinking how'd they were gonna fit all of that into one episode and honestly, the finale felt a bit rushed.
Next season will probably be heavily focused on Quinn and Debra finding about about Dexter and Dexter trying to regain his humanity, or something to that effect. The whole Liddy and Santa muerte side plots were a bit of a lead-up to that.
