This seems like straight out of Lucasfilm if they put in the proper effort in the effects. Amazing!

Since PixelJoker was participating in the Kenobi Redux thread I really hope that he is incorporating the great idea from Phase3/Broom kid of Vader getting his helmet sliced by Obi before he buries Obi with the rocks.

(https://originaltrilogy.com/topic/Obi-Wan-Kenobi-Redux-Ideas-Thread/id/94986/page/4#1492413)

It would fix the stupid ending of Obi-Wan just walking away from the fight and letting Vader live. This would explain why Obi is not so uneasy in the end scenes because Vader assumes he is now dead. His effects skills would really be needed here to replace the intact helmet with the broken one for those fight ending shots.

Maybe he wants to keep the ending details under wraps until release, but just wanted to remind about the idea. Fingers crossed…
