I'm Luke Skywalker, Jedi Knight and friend of Captain Solo."
Am I the only one who thinks Luke really WAS having delusions of grandeur, as Han said? Let's look at the points of fact.
Luke Skywalker began his training on Dagobah at the same time Han and Leia went to Cloud City on Bespin. Even if you give leeway, the longest I would say they were on Bespin was a few weeks. Now, I think this is SORTA generous, since the movie seems to imply it was a few hours or days, but that's movies for ya.
Now, if you accept a long stay of even a few weeks on Bespin, then that means Luke was in training for a few weeks, right? So, in Ep I, Obi-Wan is in his twenties, having been trained from the age of around 6 months. Twenty+ years or more and still not a Knight? How could Luke do it in a few weeks?
Ok, next, how about what happened when Luke left Tatooine after saving Han. He went back to Dagobah to keep a promise. That promise was to come back and
complete his training. So, if he knew he still had to complete his training, why did he introduce himself as a Jedi Knight? Sure, some of it might have been bravado, but Leia, Chewie, and Lando believed it enough to follow his plan.
Once he got back on Dagobah, he told Yoda he was back to complete his training.
No more training do you require. Already know you that which you need.
Luke then asked if he WAS a Jedi, and was told no.
You must confront Vader. Then, only then, a Jedi will you be. And confront him you will.
Toward the end of the film, he announces to Emperor Palpatine that he's
"a Jedi, like my father before me." Again, this seems to me nothing more than arrogance. Anakin, even before his fall, worked for more than a decade to achieve the rank of Jedi Knight, and it took a galactic war, with him as one of the legendary leaders, to give him the right to call himself Knight.
I know some of you will point out that Luke wasn't SUPPOSED to be a Jedi for this film until the end. I say that it was still many years (into the EU) before he became a Jedi. In the films, he was a weapon, trained to do what needed to be done. Yes, he has major skills, but there's still a huge difference from a private fresh outta boot and a general, having studied and earned his place as part of the elite. Skywalker was a foot soldier. Well, trained, strong in the Force, but a soldier nonetheless, not the warrior-monk that the Jedi should have been.
Anyway, that's just my thoughts on the subject....
