The Book of Boba Fett episode 4 ending teased a potential cameo from The Mandalorian’s Din Djarin (Pedro Pascal). After Boba Fett (Temuera Morrison) meets with the crime families of Mos Espa, he realizes that he’s still going to need some help in the war that’s about to come to his doorstep. As such, Fennec Shand (Ming-Na Wen) suggests that they buy help, serving as a tease for Din Djarin, the Mandalorian himself.
In The Book of Boba Fett episode 4, the final flashbacks to Boba Fett’s time on Tatooine after his escape from the maw of the sarlacc pit are revealed. It’s also shown how he came to meet and save the life of Fennec Shand, resulting in their partnership which has lasted through The Mandalorian season 2 and on into this new series’ present. Now, The Book of Boba Fett can bring its full attention to the arrival of the Pykes on Tatooine, a powerful syndicate with sizable forces who threaten the stability of Tatooine. In response, Fett hosts a meeting with the heads of Mos Espa’s other crime families.
While none of the families choose to side with Fett in his upcoming war with the Pykes, he does get them to agree that they won’t join the Pykes against him, understanding that Boba is the lesser threat to their respective enterprises. Unfortunately, that still means Boba’s forces are limited in the face of the small army the syndicate’s brought to Tatooine. This is what prompts Fennec to propose that they start using some of Fett’s newfound wealth: “credits can buy muscle…if you know where to look.” With this, the episode ends by playing the main theme from The Mandalorian, teasing a future cameo where Din Djarin himself may be recruited by Fett for the battle to come.
While a cameo from Din Djarin in The Book of Boba Fett would certainly be exciting, it’s also possible that Ludwig Goransson’s main theme from The Mandalorian could be teasing Mandalorians in general. Bo-Katan Kryze and her Nite Owls are certainly a possibility considering they helped Djarin rescue Grogu alongside Fett and Shand, though the season 2 finale suggests that they might be preoccupied with the liberation of Mandalore. Instead, it seems more likely that Djarin’s clan known as the Children of the Watch would be the ones to accept Fett’s credits (if not Djarin himself). Fennec’s line about “knowing where to look” would certainly make sense for the Watch seeing as how they’re largely based underground as a means of survival.
Because Din Djarin is now the wielder of the Darksaber and the rightful ruler of Mandalore, his time as a bounty hunter may be over (not unlike Boba himself). However, becoming a ruler is not something Djarin ever wanted, so perhaps he’s delaying the inevitable by answering Fett’s call in future episodes of The Book of Boba Fett. Either way, a future cameo (or cameos) from The Mandalorian seem to be all but confirmed as the new Star Wars show continues.
