Honestly you might be able to do it in an Addams Family way that didn't seem jarring even, like if I was writing Addamses in a modern US high school I'd probably want to at least mention it because it *would* come up, and "Pubert is formally reported as being at risk of causing a mass shooting and things spiral after he confesses to stabbing his uncle several times and putting arsenic in his mother's tea, the family end up accidentally thwarting an actual mass shooting via the power of love, acceptance and mass confusion" would be a perfectly valid comedy plot for 21st century Addamses. Still don't know that I'd dare do it for YT even with an explicit OK from the recip via the mods, but if it was done well I don't know that coal would have thought it was worth calling out.

But based on the excerpt downthread "done well" and "handling it in an appropriately Addams way" do not seem to be the case with this fic anyway so that's moot.
