NB413, now finally waking up after the fall from the "separation incident", he wakes up on a dark colored hill. The moon is up, but it's red. And there appears to be a hat-less Mario with a spear near the top. NB413 decides to face it to maybe reunite with the other. But there's a problem. Hellspawn had his gun when everyone was separated. So now he must fight with fate to survive this guy and their rule of "no survivors"
