Im not disagreeing but you're probably right. This is what I get for skimming posts lolIf we can kiss our brothers to spite our lovers, but we can't kiss our grandfathers to save their souls, then how are we any better than the space nazi terrorists, Surfinn?
I feel that this misses the point. It's not about what assy canonical line you can dig up that explains why the fake magic crystal can still power the fake magic sword even if it's two fake magic crystals.
The point is that the crystal was broken by the struggle between Kylo Ren and Rey vying for control of the Skywalker legacy, each having found failure in the ideals they pursued. The skywalker lightsaber no longer represents the thing that they originally envisioned, and that is what the broken lightsaber meant - their old, fantasized vision of the Skywalker legacy is broken. But broken does not mean ruined. it means something new has to take it's place.
Which meant that Rey should have been using the lightsaber she gets at the end. New, with her own color, based on her own staff...hers. What is a repaired Childkiller lightsaber supposed to represent other than what everything else in this movie represents, a pandering to the basest instincts the fanbase has over seeing the OT copy and pasted indefinitely.
