It’d honestly be weird if it didn’t cover at least one previously mentioned story beat (most likely either Kessel Run and/or getting Falcon from Lando). I really don’t understand this “how dare they show something that’s been talked about before!” attitude.
I mean, sure, you don’t want to see everything we know about Han and Chewie come into place in one movie. But at the same time what makes more sense, that a big event in a chronologically previous film would be mentioned in a later one, or that it wouldn’t be mentioned at all? If you don’t show at least one of the big pre-OT Han tales, it’s kind of like, what the fuck’s the point?
