^ Yes, I just meant that the saber shouldn’t appear to totally break for good during the DSII duel. I think a subtler approach should do the trick: Rey noticed it fizzling as she looks down at it, another shot from above of it, and she cowers as the saber is out of frame. Viola!
Also, it need only be a nod to the audience without having an in-universe correlate about the color of the two lights on Rey’s yellow saber. She knows the myth of Luke Skywalker anyway, so I think green and purple is the best Luke-Leia homage possible. I imagine it’s slightly better thematically that she buries the broken sabers of the past and builds her own anew anyway.
