Since checking himself out of Pineview, Norman (Freddie Highmore) hasn’t been adjusting well.

He’s come home from the mental hospital to find that his mother, Norma (Vera Farmiga) has gotten married — and it’s not just a marriage of convenience, as she initially claimed, but a true, passionate love affair with Alex Romero (Nestor Carbonell).

Norman’s jealousy has gotten so bad, he’s picked up a spying habit “Psycho” fans will recognize.

Knowing Norman’s track record for piling up bodies, it seems it’s not a matter of if, but when — or more accurately, who — he’ll kill again. In a promo for the May 9 episode (the last before the May 16 season finale), Norman is seen burying something (or someone?).

But despite Norman’s attack on Romero with an ax at the end of last week’s episode, Norma still stubbornly refuses to believe there’s anything wrong with her son.

“He’s dangerous,” Romero says in the promo.

“He’s my son,” counters Norma. “Don’t you think I would know if he was dangerous?”

Even Dylan (Max Theriot) tries to warn her, too: “You’re trying so hard to protect him, you can’t see what’s right around you.”

But as always, mother and son only have eyes for each other.

“We’re supposed to be together, aren’t we, Norman?” she asks.

“Yes, Mother,” he answers. “Forever.”

The question is: How far will Norman go for his mother? “The obsession with Norma and the relationship with Norma is always going to be the driving force of this show,” teases executive producer Kerry Ehrin. For the answer to that pivotal query, watch episode 9 and then click over to our “Bates Motel” postmortem and recap with Ehrin, exec producer Carlton Cuse and star Freddie Highmore.
