I’m going absolutely feral at the imagery here, that Obi-Wan buried his lightsaber together with Anakin’s, these two people buried in the sand, they were both supposed to be dead and buried.
“This lightsaber is your life.”
And when they died, their lives were buried in the same box in the same sand.
Obi-Wan buries them together because they died together, Obi-Wan Kenobi and Anakin Skywalker died at the same time and they were laid to rest together in the sand.
He buries them together because they loved each other and these were pieces that belonged to another age, because Obi-Wan Kenobi and Anakin Skywalker were a love story and they were brothers, they should be buried together.
But also that neither of them will stay buried.
Obi-Wan is digging himself back up, he can’t just be Ben anymore, he has to be Obi-Wan Kenobi, and he has no idea that he’s not the only one who’s going to be dug up out of the sand, that Anakin’s presence in his life will also be dug up out of that sand.
These lightsabers were their lives and I am absolutely FERAL at the imagery of them being dug up again and what that means for where Obi-Wan has to go next and who exactly is waiting for him.
