The funny thing (which in reality is so not funny at all) is that … if BONNIE hadn’t left Kai in 1903 , he wouldn’t have crashed Jo & Alaric’s wedding , Elena would NOT be in a sleeping curse (tho I think that had more to do with Nina leaving , but anyways) and the series would’ve looked SO DIFFERENT … yeah , maybe Kai was going to snap back at some point but … after watching that deleted scene from 6x15 and when he talked to Caroline in 8x14 about his childhood … He actually had a chance to be good , to change…
Even in 1994 , you could see that he cared. Maybe in a little twisted way but he did.
ALSO something else I keep thinking about … you know , even if the chains bounding Kai to that chair were spelled , at some point he’d be able to focus and siphon the magic from them (he managed to siphon the traveller’s spell , remember) and get free , change that song …. xD
Clearly the new Ascendant came from the Armoury and as Kai said “Magic is LITERALLY IN the walls.” there … Let’s not forget he is highly intelligent … maybe he doesn’t need a celestial even’t to draw from. MAYBE .. just maybe , this will all be enough for him to get out. Maybe the magic contained in the Armoury is enough for him to get free , get back to reality too.
