Just seems odd though -
exact same thing happens to Qui Gon, in theory
more powerful with force than Reva, but he's 98% dead immediately after impalement (immobile, apparently dead) then 100% dead just a min or two later in OWK's arms.
I'd just say it's not a good look - lightsaber right through you, and then minutes later you're rummaging through OWK's Jedi cellphone going "hmmm, veely interesting...."
And Vader leaving her "only half dead" (?) is just stupid and make him look like an idiot, even though I get that logic flew out the window long ago in Disney SW - Palps surving ROTJ and Maul surviving being cut in half, and yeah Book of Boba's sniper sidekick with the robot innards or whatever.
It all just becomes meaningless - like in SW you need to chop your adversary up into tiny chunks then incinerate them to make sure they are dead, but even then there's some bs explanation... every character like the T-1000.
... except if you're a stormie, where in Disney SW a brusque cough from close enough will END you.
