In the clips, it appears like Romero successfully manages to transport his wife and stepson to hospital. But it remains to be seen, whether or not he can prevent Norman from a fatal psychotic breakdown. Moreover, questions remain over Norma being able to trust her son after the horrific incident.

Speaking about the season finale, executive producer Kerry Ehrin told TV Line, "Anybody that goes behind your back to do something as gigantic as getting your kid committed, their trust would be pretty burned up at that point. And the thing that she loved about Alex was the trust."

"When it was really Norman against Romero – even though Romero is the healthy choice — I think that Norma's mental fragility [and] her history made her cling to Norman," Ehrin added explaining Norma's disastrous choices.

The synopsis of the finale episode reads as follows:

"Norman and Norma's relationship faces its greatest test yet; Romero faces pressure from all sides; Dylan considers reaching out to Norman--but wants nothing to do with Norma."

Bates Motel season 4 finale is titled Norman and will air on 16 May at 9/8c on A&E network.
