Ben Solo, tempted to the Dark Side by Palpatine through Snoke, ended up destroying the Jedi temple and Luke’s students within it in 28 ABY, as mentioned. Maybe an older Grogu was killed there? Whatever the case, we wouldn’t be surprised if he butts heads with a young Ken Ren in the future. Plus, let’s not forget that there are 25 years for Lucasfilm to play around with between the original and sequel trilogies, so no doubt there are plenty of adventures for Baby Yoda no matter his fate. There’s also the matter of just who saved Grogu from Anakin’s infanticide in Revenge of the Sith.
