So anyway back on the season finale--near the end, Glenn fights with Nicholas because Glenn's so damn angry that Nicholas basically doomed Noah to die (not to mention Nicholas tries to kill Glenn too, that scheming scumbag), and Glenn comes really close to killing Nicholas out of frustration and anger and sorrow. But Glenn doesn't, because he can't bring himself to. Instead, the two limp together back to Alexandria, supporting each other as they go. I think that's how Luke would've reacted in a situation with Kenny if Jane had died--the fight would've started somehow (probably accidentally) and Luke'd defend himself from Kenny and once Luke was pushed enough, he would've been really angry at Kenny and maybe, maybe, tried to kill Kenny, but he wouldn't be able to, like Glenn couldn't--or wouldn't--kill Nicholas. And maybe during this fight Kenny would've just seen red and lost control and tried to kill Luke even if he didn't really mean to (though I think Kenny'd have to be insanely angry at Luke to really do that), and that's when Clem would have to step in. Maybe that's why they had the hiding-baby plot thing there, because, even though Luke would never hide AJ like that, I don't know how else Kenny'd get so red-eyed to try to outright kill someone like that. Honestly I don't think either Luke or Kenny could've been pushed so far to try to kill each other really, if we take the baby-hiding thing out of the equation. Idk, you'd have to change a lot of little things to make it really really work and for the plot to make sense while still remaining true to both Luke's and Kenny's characters (which I don't think they did with Jane's character in the final fight at all) but yeah. Maybe that's why they replaced Jane with Luke, because I really don't see a huge conflict coming out of Kenny and Luke fighting like that, or it making sense for them to want to kill each other. So maybe Kenny vs. Jane just made more sense, plot-wise for TT to write, rather than writing Luke vs. Kenny did. In the game version, Telltale was just trying to squeeze out a conflict out of literally nothing, and even if Luke vs. Kenny might have worked, the game-version of Kenny vs. Jane really didn't work at all either. At least, not for me.
