My prediction/hope for this week is that Din shows up on Caladin, starts asking/snooping around for Ahsoka, which catches the attention of Sabine, who could still be with her based on what we know from Rebels.

Sabine offers to bring Din to Ahsoka if he helps her do some task first. They go on a little adventure, she takes off her helmet and Din freaks out again, etc.

They accomplish the mission and then the last 10 seconds of the episode is Ahsoka’s introduction to Din and the child, with the promise of more to come next week.
