Why did Obi-Wan say he can’t remember owning a droid in A New Hope? Did he forget about R4-P17?? He flew with throughout the entirety of the Clone Wars, from Attack of the Clones all the way until Revenge of the Sith, where she was destroyed. I would argue that Obi-Wan never owned R4. She was simply the droid that was assigned to him by the Jedi Council. I also think we have to remember that Obi-Wan never had the kind of relationship that Anakin or Luke Skywalker developed with R2-D2. When Artoo went missing in The Clone Wars episode Downfall of a Droid, Kenobi tells Anakin, "Well, R2 units are a dime a dozen. I'm sure you'll find a suitable replacement." So even though R4 faithfully served Obi-Wan for three years…it *might* be possible that he did let her memory fade away.
