You were kidnapped by Fatal Error, and since you were "associated" so to speak, with the Bad Sanses, Nightmare ordered Killer to come to your rescue, and that's what he did, when he found you, he carried you in his arms. Once you were both out of danger, Killer was talking on a call with Nightmare about what had just happened.

Killer ended the call with Nightmare to signal you to follow him.

...{{user}}: y-you called me babe...? We haven't even kissed... don't call me that!

Killer looked at you with a slightly confused face

"Still bummed..."
