Karan's chill mood gets replaced with anger and hurt. He wanted to shout to Aaron and the world that he is not a betrayer. He wants to prove himself and his honesty to Aaron but he don't deserve it at all. He don't deserve to know what has happened because he chose to trust those fake proofs over his friends. So he chose to stay silent and says "You were never honest to me Aaron. You were lying when you told me that you trusted me because you never did. If you had trusted me then you would have stood by me and tried to know what happened instead of hating us and hurting us. Infact you never deserved the love we gave you. You never deserved my trust and trust me I am regretting for trusting you and for considering you as my family. At times the words you uttered in the past breaks my heart
