“If you’re watching this, then chances are, I’m probably dead. Chewie, don’t let that crazy kid crash the Falcon too bad.”
In all seriousness, I’m not sure how I’d feel about that. It’s tidy, but Han doesn’t strike me as the kind of guy to leave a sappy note behind. He was always one to put all his cards on the table. It would work as a narrative device if done right, but at the same time would (at least to me) feel genuinely OOC.
I wasn’t thinking along the lines of Han giving a “In case I’m dead” message, but something else entirely. It could be a happy moment of him with Leia, Han, and Ben. It could be him reaching out to Ben after the incident. Who knows. Spit-balling here mostly, but I think it could work. They say becoming a father is life changing, and during that 30 year gap, he could had gone a little soft and taking a liking to record some good moments in the presence of his kid. Of course, he goes back to regular Han after he cut ties from Leia and Ben heartbreakingly so.
Of course, none of this is really needed. This is only an interesting idea to me IF Kennedy was really serious about what she said.
