How come if C3P-O was owned by lars owen and beru, when he came back to Tatooine in episdoe 4, why didn't they recognize him or he rocognize them. He could have been like 'Oh master Lars! It's been so long!' ---bboy
as to why owen didn't recognize 3p0:
exterior covering on 3po was different,
there are many other interpretor droids similar in style seen throughout the series --- in the rebel ship of episode 4 opening shot -- again we see another in bespin, -- as well as in episode 1 when quigon and obiwan act as ambassadors
as to why 3p0 didn't recognize owen:
for one he didn't really spend much time with him, but really because owen had aged greatly almost 40 years since he saw him last, at that point 3p0 could have just assumed it was another human,
with anakin it was different because anakin was his maker, programming and voice recognition of the programmer could justify this
in respect to R2:
i don't think the jet boosters would work underwater or in a swamp for that matter, also in every episode we get to see more of his equipment that is hidden behind the compartments, arms, periscope, tow wire, launcher, projector, etc even magnetized feet'
which that should be the question then, if his feet are magnetic why did he fall off the x-wing at dagobah?
