It feels like 9-1-1 knew we’d all be crushed under the weight of election week and decided, “Let’s do a silly one.” That’s not to say there aren’t heavy moments in “Confessions” — and rest assured I have feelings about those — but the calls are a lot lighter than what we’ve been seeing, without the life-or-death stakes of Denny being pinned to a house in the Halloween episode. There are also enough funny and thrillingly bizarre scenes to at least balance out the somber stuff, and for that I am grateful.
