was having a think about anakin's defeat at mustafar by obi wan, and how contrived it appears 'i have the high ground' (wtf!)

what i was thinking, was to employ a common story technique where the action of obi wan's victory would relate to some anecdote from earlier in the film, where obi wan would have learnt a lesson from a mistake.

an example of this would be during iron man his suit freezes due to the altitude. he fixes this problem. when fighting iron monger later on, he has an epiphany and leads him to a high altitude in order to freeze his suit too thus defeating him.

i was thinking, if we could create an event during the grevious duel that could relate to another created event where anakin is defeated - so basically reinvent two pivocal moments during these duels. however impossible it may be to produce, could you please give your ideas as someone else may think of a variation that is more realistic!
