Imagine if Red and Blue go to war again for real. On a moonlit battlefield, the siblings find themselves face to face; their worst fears coming true. As Katie drives her sword forward, both her and Nom close their eyes, unwilling to accept the fate that befalls them.
Nom is the first to open his eyes. He doesn't understand why he isn't in pain until he sees a small blue cloak in front of him... with Katies sword piercing through it.
Across the battlefield, Mae's screams until it dissolves into sobbing.
In a last ditch effort to save his best friend, 4C loses his life.
The battlefield goes quiet. Mae watches, helpless, as another person she cares about is ripped from her arms.
Katie and Nom lose another member of their family that was already far too small. He's failed to protect someone again. Everyone who was with him that day is now, truly, gone.
4C looks up at the moon and, for just a moment, he thinks he's made it back home.
