I'm not even showing him in the PM scenes, he's in the AOTC scenes and he's shown on the Lars' farm - why doesn't Owen remember C3PO? It doesn't make sense. Owen needed a new protocol droid would make sense though, considering they would no longer have one by ANH. C3PO is in ROTS though. He'll be Padme's protocol droid - makes more sense for her to have one, and have it be gold. It takes care of many plot holes by just making him some other protocol droid. If you guys want, I can upload the ONE scene I have of him.
