One of the new TV spots also has a cool shot of some Tusken raiders walking through the desert. Just a random guess, but this might be a flashback too. These could be the Tuskens that find Boba and rescue him.

Wild speculation, but I’m guessing that Tuskens were the one’s that found him after he escaped the Sarlacc, and maybe he has been living with them to some extent over the past few years, which explains his robes and skills with a gaffi stick.

I also wonder if we’ll find out that Boba got amnesia after being rescued. This would explain why Boba waited so long to try and get his armor back. Maybe Fennec knew Boba from before and helped him remember who he is whenever he saved her.

I’m also guessing that shot of Boba in the bacta tank isn’t from when he was initially rescued from the Sarlacc, but it’s something that he does at the beginning of the season to explain why he no longer has the facial scarring like he did in Mando S2.
