Obi-Wan Kenobi is a True Jedi.  Not because he’s mastered himself and his emotions or anything (though, that, too) but because he’s a giant fucking nerd who wants to study literal brain worms and gets mad when Anakin stomps them to death and he probably thinks the height of a Saturday night is a grammar argument with another Jedi Master about some obscure text philosophizing on the Force.  This is the only metric by which a True Jedi can be measured, I will accept nothing else.
