Mr. and Mrs. Mazikeen Smith - S3-E3
Factual error: The therapist says to stop the bleeding, Maze will have to remove the bullet and stitch him up. Gunshot wounds are complicated. To remove the bullet one must first perform an X-ray to see where it is, and after the surgery is completed, especially for a gutshot, surgical drains need to be installed till the wound heals. It's a hollow space that will fill up with bile and nastiness and drains are needed to collect the fluid, or else it will just get infected. If only it were that simple. (00:26:30 - 00:27:00)
Answer: Boo Normal and Once Upon a Time were going to be part of season 4, then the show got cancelled (before being picked up elsewhere). As such they were added on to the end of season three as "bonus" episodes, hence the continuity being off. But not really a mistake, just a quirk of broadcasting. Boo Normal was originally going to be between the episodes "High School Poppycock" and "Infernal Guinea Pig" in season 3 before being slated for season 4, presumably because aside from the point you've raised, it was fairly flexible, continuity-wise.
