I'm going to present this in a format that abuses line breaks because it's based off of a series of texts that my friend Kevin and I sent each other throughout watching the episode.
Some good subtitles this episode. Nothing that quite approaches "[Intense Ethereal Whooshing]", but hey.
"[boy] Nice!"
"[smooches]"
Norma has been going through that stack of mail forever.
The going theory in my friend group is that Carl Rodd has been killed and replaced by Windom Earle, who has trained the denizens of the New Fat Trout to follow his commands via flute. That van got to him and Shelly in like 15 seconds. Speaking of Shelly, she really just needs to stop hanging around with anyone except for Norma.
Per the credits, the minivan mom is actually Gertrude Hayward Donna's piano-playing sister from the original run.
And finally, the most important thing about the episode, which made me cry laughing when Kevin suggested it to me originally, and which is still making me laugh as I type this out. When you're watching the fallout from the gunshot through the RR window, mentally replace the lady and her drugged-out daughter with Frank and Charlie from It's Always Sunny In Philadelphia. She'd have stopped honking if only Deputy Bobby had offered her a nice egg in that trying time.
