Continuity mistake: Near the start of the show, Dr. Dave asks the patient Jesse how he's feeling and Jesse answers, "Not so well", and then begins throwing up. By the next shot, though, there is more vomit on his shirt than could have possibly got there in such a short time.
Continuity mistake: After saving Mr. Perez, Carter says "That's a nice save" to Mark, and takes his stethoscope out of his ears and wraps it around his neck. The next shot, however, from behind him, shows the stethoscope is still in his ears.
Continuity mistake: When Mr. Perez pushes Carter into the window, Carter's stethoscope is around his neck with the earpieces on the right. At one point during the fight the stethoscope is around his neck with the earpieces on the left - and then returns to the other position.
Answer: Take care of your dad.
