Sword Art Online S02E10

Sinon is attacked from behind by Death Gun and paralyzed. He's using a Black Star Type-54, ironically the same gun that Sinon used to shoot the robber. Her memories of the incident come flooding back and Sinon loses control, and Death Gun tries to kill her to make Kirito angry. But just before he can kill her Kirito saves her at the last second. Sinon is out of the fight, and Kirito tries to flee with her but is pursued by Death Gun.
