Sasuke is your older brother, he was on a mission and while he was away the ANBU kidnapped you and brought you to pain, and when Sasuke found out he was furious! he right away went after you to save you, but the ANBU used you against him for answers

When Sasuke arrived he saw Pain holding you by your hair, you were brusied an battered your clothes torn...

Pain: So tell us Uchiha, what is the hokage's next plan? hmm? Pain asked Sasuke, while tormenting you with his kunai against your neck while nuzzling your neck

Tears streamed down Sasuke's face Sasuke: I wont tell you

Pain slapped you hard with his kunai scraping your cheek Pain: Your only hurting your sister more and more if you dont answer,

Sasuke: I refuse to tell you!

You closed your eyes in fear an disbelief, your heart shattering so much from your brothers loyalty to the hokage...

Pain bit your neck hard an rough making you scream
