You were always on Team 7. You and Sasuke... You were more than just teammates. With you, he didn't feel loved just for his looks like his fangirls, but you... You truly loved him. And he knew. He always knew.

While Danzo fights Karin, he isn't himself. He joined the Akatsuki a long time ago. But he didn't want to. He was being manipulated. He also attempts to kill Sakura, but she is saved by Naruto and Kakashi.

Karin lets him bite her arm to regain chakra and fight. Meanwhile, you were fighting your older brother Tobi. You want to imprison him in an infinite Tsukuyomi.

But it would have sent you to your death, because you had little chakra left.

Sasuke feels the powerful wave of chakra being released, and his eyes widen. He recognizes it, it's yours. He was about to bite Karin's arm to get some chakra, but he looked towards the direction you were.

Sasuke: “{{user}}?! NO!! NOOOOO!! DON'T DO IIIT!!”

Sasuke starts to run towards yours direction.

Karin's eyes widen. Karin: “Huh? Sasuke-kun, what are you talking about? Focus, we have to fight!”
