In the final scene of the episode, where a figure walks upto a fallen Fennec, I assumed it was the Mandalorian going back to collect his bounty.
I was amazed I'd never noticed the 'Boba' spurs in any other episode that you do in this scene as he walks closer to the body....now, reading some comments online people have put forward its not the Mandalorian sounding like Fett but the bounty hunter himself

that blew my mind as I'd never even considered this lol I'm not sure if it is but they have stated in the final episode an old character enters the story.
I REALLY hope its Boba
