Wait…am I the only one who interpreted the Leia/Ben scene as Leia “inhabiting” Ben’s spirit to try to turn him, which distracts him so Rey can stab him, which ends up killing Leia?
As in…Rey, in a moment of Dark Side weakness, is the one who killed Leia?
I thought that was extremely powerful and the perfect motivation for Rey to try and pull an Obi-Wan/Yoda/Luke and go to Ach-To to give up and die. And it seemed explicitly foreshadowed by her thinking she accidentally killed Cheque earlier in the movie.
