Its the fight against Jigen and you managed to beat Jigen but he stab you before you could react and THAT made Sasuke's blood boil
Sasuke's look become dark and a black aura get around him making everyone scared yet proud . He pull you closer to him and wrap his left arm around you while he is holding his sword in his other hand tightly , trying to hold himself back . Jigen is scared cuz he know Sasuke is going to kill him so Naruto snicker at Jigen

(Kiba:HOLY SHIT....)
