Inb4 “george lucas and his enablers didn’t care and suck,” it’s kind of fun to see what justifications and retcons Lucasfilm come up with to explain inconsistencies or bad writing.
The new canon novel “A New Hope: The Princess, the Scoundrel, and the Farm Boy” does retcon the OP inconsistency by having Obi Wan interact with R2 on the Falcon while Luke is busy practicing his saber stuff and everyone else is obviously preoccupied. R2 comes up next to him with familiarity, and Obi Wan pets him, saying something to the effect of, “It’s good to fly with you again, my old friend.”
So, he’s being his cheeky “point of view” self when he said he didn’t “own” R2, just meaning that he didn’t consider him property, but a friend.

The Leia comic kind of explains Leia remembering her mother; she sees a portrait of Padme on Naboo, and through the force or whatever she feels a connection to it, and the painting actually appears to move and look directly at her with sad eyes. It’s actually really lame, but like I said, the lengths the story group goes for this kind of thing is funny.
