Damn it, Jar Jar! I had finally convinced Hal to use one of my own ideas! Haha

The way I see it, if Lando went there exclusively to help Rey & Co., it wouldn’t make sense for him to immediately abandon them again as soon as he tells them about ye olde clown Ochi. Why wouldn’t he at least help them get to the ship? Distract the First Order? Anything?? Why’d he bother coming at all? Just send a holo-message to them on the Falcon and save yourself the trip. It’s dumb.

But more importantly - as I’ve said before - we also have to consider dramatic tension, not just what the Wiki says are the dry facts of the mission. (And the Wiki says he was already on Pasaana anyway, soo…aha?) It’s better storytelling if we don’t know whether or not to trust Crossbow Man until he reveals his identity. If he tells us, “It’s okay, I’m a friend of Leia’s!” Then there goes any sense of suspense. Oh, it’s just Lando…Great.

Besides, removing the line doesn’t mean Leia didn’t send him a text. It wouldn’t contradict anything in your headcannon; it would just make the storytelling more impactful.
