Exactly.

He went into DEEP hiding, keeping an eye on the boy as directed by Yoda.

If all he did was cut up giant sand fish out in the desert and go to Mos Eisly to get the occasional supplies, how would he know?

I like the story so far with Obi Wan. Do not like Reva at all, terrible actress and storyline. The Princess Leia rescue comes very close to breaking canon... I just rewatched A New Hope and Leia doesn’t really react to Vader “killing” Obi Wan. She just puts a blanket on Luke’s shoulderes and says “There’s nothing you could have done...” Not a thing about knowing Kenobi as her previous rescuer and companion.

Anakin becomes Darth Vader: ..."henceforth, you shall be known as Darth Vader."

Obi-Wan learns the truth of Anakin becoming Darth Vader (referred to by that name *twice* - by the Emperor he personally sees on the security footage - “You have done well, my new apprentice. Now, Lord Vader, go and bring peace to the Empire" - and in follow-up conversation with Yoda that Skywalker is gone and has been "consumed by Darth Vader" - “Twisted by the dark side young Skywalker has become. The boy you trained, gone he is. Consumed by Darth Vader.”

Also they had not met since their last battle per the dialog in Episode 4: A New Hope: "I've been waiting for you Obi-Wan...we meet again, at last. The circle is now complete. When I left you, I was but the learner - now I am the master.
