In this episode, The Armorer (Emily Swallow) makes Grogu a new piece of armor for protection. While watching her creating the piece, Grogu suddenly gets a flashback of Order 66.
Previously, in The Book Of Boba Fett, Luke Skywalker (Mark Hamill) unlocked Grogu's memory of Order 66, but we only saw a portion of what occurred. However, everything soon comes into focus this time. It gives us a full look of what happened on that fateful night. As the doors open, it reveals the person who came to save Grogu.
Grogu's savior turns out to be someone that fans already know too well: Jedi Master Kelleran Beq (Ahmed Best). If you haven't realized it yet, Ahmed Best is mostly known for playing Jar Jar Binks in Star Wars prequel trilogy. How glad we are to see him back!

 

#2. How Did Grogu Survive Order 66?

As we all know, on that night, Palpatine was ordering his soldiers to brutally execute every Jedi. The situation at that time was extremely dangerous, with Grogu's life hanging by a thread. All of the Jedi who were supposed to protect Grogu had died already. Grogu's guardians were able to get him to an elevator, which took him to Coruscant's Jedi Temple.
Beq was one of the remaining survivors of Order 66, and luckily, he appeared just in time to save Grogu. With two lightsabers in his hand, Beq skillfully fought against the soldiers, which helped him and Grogu have some time to escape.
Taking Grogu with him, Beq flew through the night sky of Coruscant in the speeder. They were chased by waves of clone troopers, but Beq managed to dodge all of the attacks. With Grogu by his side, Beq boarded a cruiser and successfully escaped with the assistance of some Senate guards. The interesting thing is that the cruiser that Beq and Grogu got into in fact belongs to the Naboo Armed Force.

We didn't see the events occuring after they left the Core Worlds, as well as the reason the Naboo decided to help them. However, the time span between Order 66 and when Din discovered Grogu was pretty lengthy. Therefore, we could hopefully get to see Kelleran Beq appear in another flashback, revealing some of the details about what happened to Grogu and him.
