So Han and Lando only knew each other for a relatively short time across two or so adventures?
Says who?
Upon further reflection, I conflated the implied incident behind the “well that was a long time ago, I’m sure he’s forgotten about that” that Lando pretended to be pissed about in ESB with Han winning the Falcon. Which doesn’t even make any sense.
But in my defense I haven’t been getting a lot of sleep.
