There's a lot to discuss here because there is a bonkers backstory for R5-D4. It's up there with IG-88's. I think the Expanded Universe writers love their droids.
R5-D4, Arfive-Deefour, or Red as Luke Skywalker called him, was a white and red striped R5-series astromech droid on Tatooine.
Thanks everyone! See you next week.
