well......considering the trend.......he HAS to beat her in some way that nearly kills him as well.....
considering that he feels the same impact delivered to the victum of his jutsu, i would think that he would indeed catch her in his shadow, have her command the summons to attack her, and then shikamaru and her both would recieve serious wounds
i mean cmon....all the other genin's are doin it.....why cant shika sacrifice himself too??
