One thing that bugs me is Hasbro calling some droids Imperial. There was the R4 from the Imperial TRU pack, which is not an Imp despite his black/blue color. He was in the Yavin hangar rolling behind Han and Chewie while they were packing up. Then, R2-Q2 and R4-M9, both called Imperials, when they are both seen in Rebel areas such as Yavin hangar and Hoth hangar, respectively. Did anyone think, when seeing them rolling down the Tantive corridor in front of the captured rebel troops, that they were Imperial? I've always assumed those 2 were "marching" just like the captured troops. Isn't that an easier explanation, seeing how we see them later as rebels (or some identical to them)?
