Given how “”“meta”"" the ST has been, Luke’s words (presumably to Rey) in the teaser could continue this. The message would carry on what TLJ seemed to state, that these stories, characters, and archetypes will always be with us, the audience. As we leave Narnia and return to our lives, hopefully they will spur us toward greater things. We are broom boy, and it seems like TROS will send us off by concluding the ST’s ‘meditation’ on Star Wars itself, and its meaning for all of us. Seems like about the only satisfying way to go with one final film, given the direction 7 and 8 took us.
