Last night brought the second season of A&E's breakout 'Psycho' prequel drama 'Bates Motel' to a close with "The Immutable Truth," as Norman (Freddie Highmore) and Norma (Vera Farmiga) were forced to confront the boy's darker side and answer for the mysterious murder that capped off the first season. Now, producer Kerry Ehrin previews the turbulent landscape of season 3 and explains some of the finale's creepier moments.

You're warned of spoilers for all of 'Bates Motel''s second season as well as potential season 3 plot points, but last night's finale "The Immutable Truth" saw Norman just barely passing a polygraph test to exonerate him of Blair Watson's murder, as Norman's hallucinations of his mother became a fully alternate responsibility that claimed responsibility for the deed. The dissociation enabled Norman to pass the polygraph by keeping the personas separate, though in the process unleashing a darker side we'll see more of in season 3.

Speaking to TVGuide, executive producer Kerry Ehrin previewed that the finale's other events could set up a strong story for Dylan Bates (Max Thieriot), while they similarly hope to incorporate Emma (Olivia Cooke) and Sheriff Romero (Nestor Carbonell) more strongly into the Bates family:

There's this whole thing about the city. What's going to happen with the drug trade and how is that going to affect the city? Plus, there's the motel and the road and [the Bates] becoming more isolated. Season 3 is definitely about a deepening of the family. Emma is going to be pulled more intimately into the family. Norman will be trying to look after his mom a little bit more, maybe run the motel more. He's going to be graduating from high school and trying to step up and be a man in the traditional sense of what that word means. But all the time he'll be fighting this darker part of himself, the question being which side will win.

As for the finale's most uncomfortable moment, which saw Norma breaking down and kissing her son as part of a plea for Norman not to kill himself, Ehrin revealed to EW that she and co-showrunner Carlton Cuse entertained several ideas for the scene, though ultimately Highmore and Farmiga's performances won them over to the most taboo version. "It kind of scared me at first. Carlton [Cuse] and I talked about it and we were like, 'We’ll make sure that we have one where they don’t kiss,' and I think the way that they did it and the way that Vera [Farmiga] kissed him was so brilliant and so perfect and so understandable in that moment that they got away with it."

'Bates Motel' will return for another season in 2015, but what say you? Were you satisfied to see Norman going even more 'Psycho' over the course of a second year in White Pine Bay?
