Maul sees Tattooine because of Obi-Wan, Ezra because Luke is the key to defeating the Sith. So if they go to Tattooine to save Obi-Wan, they’re going to assume that Ezra just saw into Maul’s vision, not that it was the answer to his as well, and they’ll just leave.
Episode ends with Ezra-aged Luke, watching the suns set and a tiny Ghost taking off in the distance.
Exactly, that’s what I was trying to say.
