Concept: Instead of having an epic death at the hands of Vader obi-wan decides on a different approach
Vader: when i left you i was but the learner now i am the master
Obi-Wan im sick of this shit kenobi: Ahh yes but have you finnally mastered getting an egg out of your mouth intact after putting it in
Obi-Wan: Oh reallllllllllllly now when you were saying that it was soooooooooooooooo easy back then
Vader: (deeper contemplative silence)
Obi-wan: nothing to say have you now this coming from the same person who when he was 10 was told that he talked peoples ears off and decided that he would to literally try do that YOU TALKED FOR 12 HOURS STRAIGHT ANAKIN AND YOU COULDNT SPEAK FOR A WEEK AFTERWORDS, though the quiet was nice
Obi-Wan: you think I’m done yet? no, good we can keep going mister “bug eating Coruscanti champion”
Vader: softly (okay ill stop)
Obi-Wan: oh you'll stop????? hmmmmmmm?????
Obi-wan: good now get on that hunk of junk were leaving
Anakin: yes master sorry master
