Some minor spoilers ahead. Fair warning.
Episode 9 (S2E1) saw our hero return to TattooineTatooine looking for another Mandalorian. Instead we find someone in some familiar green armor trying to pretend to be one (which makes Mando none too happy). Anyways, they strike a compromise to fight a Krayt Dragon and Mando gets the armor back. But the episode ends with someone watching Mando riding off into the distance, and this person turns around to face the camera.
Everyone and their dog is saying it's Boba Fett.
The question I have is how were we (the audience) supposed to know it was Fett? The last time we saw him he was kinda being dragged to his presumptive death inside a sarlacc, still wearing that armor.
