I guess I'm losing touch

When Dickson got mad, that was called seeing red. That righteous, treacherous, punishing anger...

Reyn, too. He could make literal practical use of his rage, when he was up to it.

And Shulk? Hadn't he seen red (white, gold, blue), in more ways than just the melting sight of a childhood best friend's blood dripping and drying on sleek metal claws could provide?

Shulk was a blind lamb, doing as Zanza had guided. That was what scared him: that now that he was free, his inured identity would erode to an invisible soul incapable of anger, of love, of will.
