Random TLJ thought, but I find it very interesting and clever that early on when Luke asks Rey, “Where’s Han?”, the next shot immediately cuts to Kylo/Ben.
Then later in that scene with Snoke and Kylo, Snoke demeans Kylo by saying something along the lines of Kylo still having his father’s heart.
Then near the end of the film when Luke confronts Ben, Luke tells him how he would always be with him, just like his father. Then his final words, which are to Ben, are clearly something Han would say, “See ya around, kid.” This clearly shakes Ben.
Soon afterwards, Ben finds Han’s dice, and while they physically disappear, Han’s presence does not. For as hard as Ben tries to eliminate the physical manifestations of his past, the past will always be a part of him; it will never leave him, just like Han.
“Where’s Han?”
With Ben Solo.
