Did You Know?


The scene where Dean breaks into the house to steal the silverware and Sam interrupts him is a throwback to a very similar scene in the beginning of the show's pilot episode, even including some of the same dialogue. See more »


The plot holes regarding the alternate "reality" would not be plot holes because it is a fantasy created for Dean by the djinn, using Dean's knowledge. Since he has not gone back in time yet, and does not know about Mary's deal with Azazel, the djinn would not know to build these into the "reality". The fact that Mary hasn't aged probably should have been a tip off to Dean. See more »


Sam Winchester: Since when do you call me Sammy? Dean, come on. We don't talk outside of holidays.
Dean Winchester: We don't? Well we should. I mean, you're my brother.
Sam Winchester: You're my brother? You know, that's what you said when you snaked my ATM card, or when you bailed on my graduation, or when you hooked up with Rachel Nave.
Dean Winchester: Who?
Sam Winchester: My prom date. On prom night.
Dean Winchester: Yeah, that does kind of sound like me.

At first glance, this episode is wonderful. Funny, achingly sad, and adorable all at once. But look a little deeper and you'll find that What Is and What Should Never Be shows a level of sophistication, acting, series and character continuity, and polish, that will blow you away.

Jensen Ackles knocked this one out of the park. Though he always does an exceptional job, he really took it up a notch this time. Never an off moment in the whole show. I have heard him referred to as a subtle actor before, and I think that comes through in this episode. The facial expressions, the gestures and movements are all spot on. You don't have to wonder how his character is feeling; it's written right there on his face, and in his eyes, for all to see. He's heartbreakingly sincere. Spectacular. Jared Padalecki also did an excellent job in this one.

A definite must see for newcomers and regulars alike.
