Why my wife hated Episode 6 of "Bates Motel", "The Truth" review

This is a guest post from my wife:

What a disappointing load of bollocks this episode was! I've loved this series so far so I'm really pissed off that this was such a shallow, obvious piece of crap.
I love it when I'm watching a film or TV program and I say, "Wow, I didn't see that one coming!" Well, this certainly didn't happen here. I saw the ending coming as soon as Norma (Vera Farmiga) went to a motel room for a bit of nooky with her dodgy lover.
It didn't make sense! Norma should so easily have said to the deputy, "Sorry, the boys will be home soon" or "Take me now, here on the patio" or even "Not tonight, I have a splitting headache."
But no, off they toddle to do the dirty in the motel room close to Jiao, the escaped sex slave. STUPID STUPID STUPID. Norma would not have done this.
The other predictable bit of writing came with the obvious physical similarities between Dylan and the bent cop, Shelby. You knew that at some stage there would be a confrontation between these two and we wouldn't know which one would make it after the shootout.
What a disappointment. Perhaps the writer(s) have used up all their good ideas. I don't know whether I'll be watching again. Maybe just one more time, to see if this was just an anomaly.
