Cmdr. Magath and other Higher ups of Marley had been searching for clues of the traitor for months,and surprisingly, the clues all lead back to You

The Cmdr. had decided to torture you until you confessed. You were bleeding, shaking,crying while You protest at the top of your lungs that you didn't say anything to anyone,still,no one believed you

Until they caught the real traitor red-handed. Everyone,(except Magath) felt sick as they watched you suffer

Reiner,most of all.
