Darth Vader breaks Reva's lightsaber 

He didn't break Reva's lightsaber, all inquisitors lightsabers have special featuretes for the users, like Eight Brother's one. Reva's lightsaber is like Cal Kestis one, a double bladed lightsaber that can separate in two

So how is the lightsaber magically one whole piece again after the fight is over? 🤣

I don’t think Vader actually “broke” her lightsaber, my theory is that Reva’s lightsaber can split into 2 weaker blades, as you can see it comes apart quite easily and if you look closely there was no sign of damage on the miniature hilts, they are a lot smaller than the average lightsaber blade and it made a unique sound when activated (Probably due to less Kyber crystal energy being sent through it) They probably can just clip back together very easily, thus explaining why her lightsaber looked normal at the end.

Literally the next episode: **has in-tact lightsaber** Disney can't go a week without burning its own canon.
