Character mistake: When April goes to see Hank at his motel, he states her romantic feelings for him are a result of "Nightingale Syndrome," however, the Nightingale Effect is caused by the caregiver developing romantic feelings for the patient, not the other way around.
Royal Pains (2009)
1 character mistake in season 1 - chronological order
Starring: Mark Feuerstein, Paulo Costanzo, Jill Flint, Reshma Shetty
Continuity mistake: Divya places a pizza slice on the table in front of Hank with the pizza crust toward the right of the screen. In the next shot with Hank's arms still at his side, the plate with the pizza is now positioned further to the left of the screen and the slice is turned so that the crust is now on the left.
Trivia: Evan was originally written as Hank's best friend. But when Paulo Costanzo was cast, his physical resemblance to Mark Feuerstein inspired Andrew Lenchewski to turn the characters into brothers.
