I honestly feel like Jackson will win. But he doesn't have room for error... he can win 6-3 at best probably but I feel like a 5-4 win.
Jackson - Jack, Analyse, Nick, Nicole, Cliff (he doesn't
need both Cliff & Nicole, I could maybe see Tommy voting for him while one of Cliff/Nicole votes Holly

)
Holly - Kat, Jessica, Christie, Tommy (first 3 are locks for Holly IMO so that's why I say Jackson wins 6-3
at best)
For some reason Nicole seems like she could be the deciding vote again... not fully sure who she'd vote for though so I could see it going either way.
Based on the speeches, I expect Jackson to do a lot better with that. Plus just the basis of Jackson fighting harder for Holly to stay than she did should be noted by everyone. Will this jury then vote Holly anyway? Idk... I could still see a scenario where only Jack, Nick and maybe Nicole vote for Jackson but my first instinct for this finale is a close Jackson win.
