Some Star Wars fans have brainworms. These are the same people who thought Kleya was actually Leia in disguise. Fortunately, Tony Gilroy shut the "Kleya=Leia" theory down. Unfortunately, it's out of his hands now, so any hack writer Lucasfilms hires is free to retcon Cassian and Bix' kid actually being Poe into existence. If that happens, I will mail said writer my own shit.
Andor/R1 is a masterpiece, and if the other writers at Lucasfilms have any amount of functional braincells numbering at least in the double digits, they'll leave it the fuck alone. No tie ins, no cameos (aside from legacy characters), none of that bullshit please.
