I never realised how quite a few of Obi-Wan’s teachings to Luke play a part in the latter and Kylo’s fight on Crait.

The biggest being when Obi-Wan states -

“Your eyes can deceive you, don’t trust them.”

During the same teachings Obi-Wan the following occurs -

Obi-Wan - “Remember, a Jedi can feel the Force flowing through him.”

Luke Skywalker - “You mean it controls your actions?”

Obi-Wan - “Partially, but it also obeys your commands.”

In light of George’s comments about the Whills and Midi-Chlorians I feel it connects another layer to the lesson and what is and isn’t destiny and free will.
