Angel/Laguerta thing will come back and there will be a you-know-what storm.
Also, Dexter holding Arthur's sister's ashes was an awesome scene. I heard Arthur coming back and was all "PUT THE VASE DOWN. GONNA GET CAUGHT

" Turns out Dex was testing him, given his demeanor in how he turned. Awesome scene though. Starting to wonder if Arthur's whole family knows that he kills people. Note how his son, at the build, went back to work ASAP after getting a glare from his old man. It'd also explain why he's so caring and relaxed around them. Sounds far-fetched, but if the mom was the same as him (or accepting), the kids could easily have been raised to know/respect the old man's dark passenger.
Hopefully this ep also will shut Rita up for a while. You know another semi-arc will kick off regarding her, though. She won't stay quiet the rest of the season.
Also, after seeing the vacation murder thing line up, I'm thinking it actually was Anton that capped Lundy. As out of character/odd it sounds, it fits best by this point. The girl confessed to helping with the murders, but not Lundy. If she was a fanatic, she would've accepted Lundy's as well. She wasn't pressured or forced in to admitting credit for the others. Plus, the show seems really strongly angled toward Trinity having done it. Seems like a red herring. Anton vanished entirely, as well (of course there was the abrupt break-up to cover that). Trinity would've finished her. I find it odd, though, that Anton would've aimed for her abdomen, something that could've been a definite kill shot if he was off.
As much as I didn't like the idea, Anton seems like the ideal murderer by this point.
