No One Is Ever Really Gone .

I think everyone’s anticipating Luke’s return in some way, shape or form. I have my doubts that he’s still alive (but if they can explain it in a way that makes sense and doesn’t feel like a cheap retcon of The Last Jedi, I’m here for it), but I’m sure he’ll be back as a Force ghost.

I interpreted that quote as a reference to all three members of the original trio, though—in that moment, it references Han in a spiritual sense and also (unintentionally) alludes to Carrie’s passing, while also foreshadowing the death of Luke (and presumably Leia) and a return in either a physical or spiritual sense.

Regardless, though, I will bet you anything Luke is in Episode IX in some form, especially being that Carrie Fisher won’t be in the film now.
