After defeating Deidara, Sasuke asks him where to find Itachi. Deidara refuses to give up and claims he still has explosive clay, but Sasuke doesn’t believe him. Enraged that Uchiha is once again looking down on him, Deidara promises to prove the superiority of his “art” over the Sharingan. Sasuke deactivates the Sharingan, which he no longer needs, prompting Deidara to take desperate action. After apologizing to Toby, Deidara uses his C0, intending to blow himself up to take Sasuke and everything within a ten kilometer radius with him.
