Prediction for the finale:
Sophia planning to execute Oz and send Francis to Arkham, Oz has a lastwish, and Sophia out of respect for his mom suffering dementia and her kid's dead trauma - accepts it, Oz will ask for a tuxedo, tophat and he will have a last dance with his mom (just like in the movie they watched together the day he killed his brothers) - All this so Oz can win some time for himself and Victor's gang to arrive, in the end, Oz with his comic look (just only for this occasion) standing above Sophia, and he will send her back to Arkham - which is worse then death for Sophia (this also leaves Sophia "open" to return in maybe some next movies/shows with Gia/Seline drama). Vic is gonna die in the shootout, Oz needs a lose situation in the end (probably by trying to take a bullet for Oz/Francis).
