Continuity: When Max, Michael, and Isabel are at the taco stand discussing Max's saving of Liz's life, you can see Michael hand Max the bottle of Tabasco the three are sharing, and when the shot switches, Michael again has the bottle of Tabasco.

Continuity: After the car gets pulled over and the sheriff says, "You kids be careful out there," Max shifts from looking at the sheriff to looking straight down between shots.

Plot hole: In the lab when Liz makes the slides of her cheek cells and the cells from Max's pencil, the first time she doesn't add stain and the second time she does. If she's going to be a molecular biologist she really ought to learn to apply techniques consistently.

Continuity: When Max heals Liz, he has his left hand on her stomach (pinky down, thumb up). But when we see the silver handprint, it is of a right hand (pinky up, thumb down).

Continuity: At the restaurant where Max, Michael and Isabel are talking, Max is sitting at the end of the table. Isabel walks up with her food and sits down right next to him. The tables have bench seats, so she can't just sit down - she would have to step high over the bench or sit on the other end and slide next to him.
