Not sure which film, but it was Kenobi going to someone’s apartment either underwater or in a terrible rain storm. Some kid answered the door
That kid was Boba Fett. I am not joking.
Ah. That explains why, in Bad Batch, they reference Omega and Boba Fett so often. Something about the two of them being different than all the other thousands of clones, as well as Clone Force 99 being another sort of exception.
