I can strongly advise re watching TPM on magic mushrooms, it will clear your mind of any notion that Vader made 3P0, in fact I can arrange a mind wipe if you truly want this memory gone for good. I tried it on my self and got the Sound of Music confused with ESB, the results where amazing. I'm still convinced Yoda got an oscar, and can clearly see him receiving the award on a hill side in Austria IN MY MIND. If nothing else it helped me forget about TPM for ever.
Always remember there only films.......as I walk into a room in my house with star wars props and models in every direction......only a film....Guy.......only a film..........
