Also, Fennec just so happened to show up at the mechanic’s shop to look for Mando the same exact day Mando was there to get his new ship?
Watching the episode a 2nd time I noticed that some of the extras used in chapter 3 when one of the mods reported on the Pykes arriving on the public transport where used in this episode as well when Din arrived at the same port with the same type of ship. It could of course just be that they just re-used the same extras for the same set (maybe even shot both back-to-back), but it could also be that Din arrived during the events of chapter 3 and that it took a while for the starfighter to be built and for Fennec and her “spies” to find out he’d arrived on Tatooine.
And the building montage suggested that at least one day passed as we saw it turn dark. Though I’d guess that it was longer.
