Best argument for Shaw being there is that WE JUST SAW HIM DIE.
The Shaw we saw die and the one who appears as a ghost look very different.
Once again, if you think his ghost should have been scarred, then Obi-Wan’s ghost should be missing his lower half.
It’s clearly the same man.The difference is that Obi-Wan wasn’t cut down until he died. Shaw’s ghost is appearing as someone who never existed.
I get it. You like the horrible PT films. It’s just easier for me to say he never looked like Hayden because that character never existed for me.
It’s still backwards thinking though. The PT kool-aid has poisoned your mind.
