If there’s been one big trend in this season of “The Mandalorian,” is that every obvious theory fans dismiss because there’s no way the show will do that… is exactly what the show ends up doing. Whether it’s Ahsoka showing up at the beginning of her episode, or name-dropping Thrawn, it has become clear this show isn’t afraid to go big. This is to say, that Luke Skywalker showing up was something we kind of should have seen coming.
