Is Obi-Wan already a Master in AOTC?
I was always unsure whether Obi-Wan was ever a literal Master at all. After all, he was pretty young when the Order was wiped out and they may never have had an opportunity to make him one.
Many people have been of the opinion that he would be a Padawan in ep. I, a Knight in two and a Master in three.
But in the Forbidden trailer, Amidala clearly calls him 'Master Obi-Wan'. Open to interpretation, but that DOES suggest he has already made it. That WOULD be young.
Then again, the term 'Master' has never been defined. It may actually just mean someone who has a Padawan, for all we know.
