This is Lena and I'm looking to come back with two characters: Wanda Maximoff & Luke Skywalker.
Wanda will be from post-WandVision, because hello regrets!
Luke is TBD, but he will probably be from just after Return of the Jedi, although I might be tempted to change that to That One Show so he can have Grogu, but I think ROTJ is a better canon point of regret, so that is more likely atm!
