This episode reminded me what the Norma/Dylan drama was about. I think it was the "I'm mad you aren't taking care of Norman! I guess I'll just leave forever!" thing that was a bit weird.
Also, some of those confrontations were kinda cringe.
"You know how Norman is kinda sick? Uh... I think he killed his dad and your teacher... and probably your mom."
And Norman being like, "Your husband is cheating on you," in response to "Why should I talk to him?" I mean she did tell him there were marrital problems, he could've based it on what she said instead of dropping a bombshell at an inopportune time.
Apparently Marion was in the first episode of the season when Sam came in to the motel. I didn't notice until last episode when it came up at some point.
