How might SNW explain the physiology of the Klingons that have ridged foreheads versus the smooth foreheads that come from the failed augment experiment in ENT? A refresher: during the run of ENT, Klingons attempted to replicate the experiment of Human Augments. It ends up failing, which results in the physiology of the population changing, thus giving a in-universe explanation for why the makeup in TOS varies from how they appear TMP and onward.
How might SNW address this bit of lore? TOS takes place during 2265-2269. SNW first episode “Strange New Worlds” is 2259, six years prior. We already know Klingons with ridged foreheads exist thanks to DIS. We even see some during “The Broken Circle”. Might one possible way of explaining the change be a shift in the military and/or political factions of the Empire that lead to more of the smooth foreheads Klingons dominating?
The revised Trill makeup in DS9 made that show literally unwatchable!
EDIT: In earnest, I do find the hoop-jumping process of trying to find some canon explanations/connections a lot of fun, as long as nobody takes them too seriously (hard mode).
I think it’s great fun to try and puzzle these things out, as a fan. I also think it’s mind numbingly tedious to sit through an entire professionally produced episode designed to do it for us. Trials and Tribble-ations handled the matter perfectly.
