I have always bumped into something that I want to bring up. The original crawl states that Kylo “rages in search of the phantom emperor, determined to destroy any threat to his power”. The film supports this by showing that when he arrives to Exegol the first thing he does is turn on his lightsaber before getting down the temple and also the first thing he says in retort to a seemingly benign statement by Palpatine is “I killed Snoke, I’ll kill you”. The movie makes it very clear that he’s going to Exegol to kill.

However, Ascendant’s crawl says that what he seeks on Exegol is a “hidden power that would allow him to destroy any threat to his rule”. This is not reflected in the behavior that he shows in the film. If his mission is really to get this power it would make little sense why he would be so confrontational and gung-ho on killing whatever is on Exegol. Sure, he has always been an erratic character but you would imagine he would be in a more exploratory attitude if he still presumably does not know how to retrieve the power he seeks. I think it runs the risk of muddling the character motivations. Is he there to retrieve a power or is he there to kill it?
