Luke then asked Mando if he could take Grogu with him to teach him the ways of the Force, since Luke is a Jedi Master. Grogu protested at first.

“He wants your permission,” Luke said during the finale. “He is strong with the Force, but talent without training is nothing. I will give my life to protect the Child, but he will not be safe until he masters his abilities.”

Was Plo Koon going to show up in ‘The Mandalorian’ finale?

In order to fool cast and crew members, the show creators wrote a fake script, which explained that the legendary Jedi Plo Koon showed up to save the day.

The script explained Plo Koon showing up on the Imperial ship’s bridge, lowering his hood and then defeating the Dark Troopers, much in the same way that Luke Skywalker did in the final.
