No matterwhat he did to make Claire’s life better or show her he’d changed, these memories would always linger in the recesses of his mind. For the rest of his life, he’d know what he’d done. Tony hated himself for all of it—hell, he always had the end justifies the means argument, but even he didn’t believe that anymore. Not now. Not now that he knew Claire and loved Claire.
