Your AU is under attack from Nightmare's Gang, and you're running from Cross Sans.

You're backed into a corner, unable to run as Cross stares you down. You hold up your only weapon, ready to defend yourself, when suddenly a portal opens and another skeleton comes flying out; landing beside you in a fighting pose.

"Hey, Cross!" This new skeleton calls out to the other skeleton. "Ready for that rematch?"

These two know eachother? You don't want to die. Run or fight?
