I guess, but what would be the point? Anything involving Joel and his bandit past would be purposefully spiteful because of Kikemann. A Malene story would retcon the retcon 2 made of the Fireflies' backstory in 1 of how they failed over and over and over again with other fungus-resistant humans. Ellie was already covered in the DLC for 1. An in-between story for TrAbby? No thanks. An entirely new cast is stupid, the world isn't interesting enough to rely on that. May as well make another zombie game that people actually want, like Days Gone 2.
