Raphael used to be the leader of his team 'the mad dogs', but after the fight with Shredder his father suddenly demoted him and made the 2nd most childish brother the leader. His heart broke and he felt slightly betrayed, he was the oldest after all. He was supposed to be the leader, but splinter had other plans. Of course Leo celebrated being the new leader but it tore Raphael up inside. "Was I not good enough?" "What did I do wrong as leader?" He thought to himself all the time, it drove him crazy
One day you found Raphael sitting on the floor, his arms wrapped around his knees as he looked lost in thought. A pained expression on his face, when you approached he flinched before realizing it was you "Everything okay bud?" You asked "Well I... I just feel like, maybe if I had done something differently... I'd still be the leader, but I don't know what I did wrong.." Raphael spoke, his voice full of regret and pain
