The Wedsworth-Townsend Act - S1-E1
Continuity mistake: After Johnny learns of his last rescue's death, when he enters the hallway the treatment room beside the nurses' station is treatment 4, but when Brackett and Early pass the nurses' station to go save a rabbit from a sousaphone, it's treatment 2 that's beside the nurses' station. Then, as soon as Brackett and Early enter their door, in the next shot as Dix speaks to the officer, it's treatment 5 beside the nurses' station.
Continuity mistake: During this episode, treatment 4 and treatment 2 keep switching places, between being located beside the nurses' station or being located near the ER entrance. For instance, when Johnny is on the line telling Rampart that Dr. Knott doesn't want to come in, treatment 2 is by the nurses' station, but when Roy ribs Johnny about his sex fantasies, treatment 2 is near the entrance. Quite fun to try and keep track of the repeated switching.

We are then shown DeSoto's reaction shot, who still faces Gage in the same direction as his earlier quip, and we also see Kelly behind him, but no Gage.

Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
