The morning Test Call, just before the final Call Out of the episode, is stock footage. The Captain is seen rising from bed & placing suspender straps from what would be Turn Out Gear, over his shoulder. The scene of the team entering the Engine during the Call Out & then driving from the Station bay is also stock footage.
Second time a possible amputation is considered. This time, Dr. Brackett leaves the hospital with Dixie. The first time was #2.21; "Audit." Dr. Early went to the site of that event.
Tenth time Dispatcher is seen, but it is stock footage.
