In the Last chapter we saw itachi doing Ameterasu, And in this chapter sasuke was finally caught with itachi's ameterasu. Itachi disabled the jutsu after seeing sasuke burned to the ground. When itachi came closer and was supposed the pluck out sasuke's eyes, he saw sasuke melting to the floor. It turned out sasuke used orochimaru's variant of kawarimi. Sasuke unleashed his level 2 and hit itachi's right arm with katon. Both uchiha brothers were left of without any chakra, but sasuke said that he had been ready for anything and said he has one more thing off his sleeve.
