So, looks like Norman is checking himself out of the hospital. He's not very happy about Norma's marriage.
The previews said "Only 3 episodes left" NOT for the season. I assume the series ends? If so, and if it follows the film, Norman should kill and stuff his mom.

Don't know about Romero or Norman's brother Dylan. I'm guessing it'll probably end where he is the owner of the Bate Motel. Of course mom will be somewhere in the house in a rocking chair.
This is of course, is my guess if there are only 3 episodes in the series left.
