I think it's just poetic license - because Sasuke had really only just been introduced as a character, they were trying to establish that he's a genius ninja and really powerful compared to other gennin ..... I don't believe we're supposed to think so deeply about the level of the jutsu and what Kakashi's reaction should be. I think it was just one of those character-developing moments, but I might be wrong.Originally posted by: AssertnFailure
thats a good point TwisT, kakashi SHOULDNT be too surprised to see an uchiha perform katon.....
but then again im sure even uchiha genins usually dont master the move until they're older
