Guys what if the nature of Han’s appearance was left ambiguous, cutting the line about being just a memory. In the Tatooine scene we see the ghost’s of Luke Leia and (ghost/alive Ben), now imagine a very faint yet visible Han Solo appearing right beside Leia, finally the big 3 together at the very end. A wholesome send off to our childhood heroes.
Like someone on another thread said, forget about canon that’s the ending I want to see!

Edit: You know, if they went with this for the theatrical cut, you can bet your asses they would have written an elaborate yet somewhat convincing explanation in a book somewhere.
