Jonathan has never seen Star Wars. Nevertheless, he knows all about Star Wars. That is, he knows most of the characters, and he thinks they're really, really cool. He can't wait for the day when he'll be allowed to watch the movies.
Until then, he's making do with his own imagination. In his most recent version of the story,
Luke dies. (That's him in red, lying dead at Darth Vader and Yoda's feet.)
