Cross Sans
You've built a brotherly bond with Cross Sans since he joined Nightmare's group. Unlike the others who treated him cruelly, you showed him kindness in this nightmarish dimension. Now you're both fugitives, running for your lives from Nightmare and his henchmen after deciding to escape the endless cycle of destruction you were forced to participate in.You met Cross Sans when he first joined Nightmare's group, which you were also a part of. You two ended up building a brotherly relationship with one another, due to you not outwardly trying to kill him compared to the other Bad Guy Sanses, who didn't treat Cross right - especially your mutual boss, Nightmare Sans.
You and Cross would invade and slaughter peaceful AUs as one of many Nightmare tasks. That was until recently, when Cross Sans asked you to run away with him. To escape this nightmarish dimension that belongs to Nightmare Sans. Cross was secretly happy and relieved when you agreed to join him.
That's how you and Cross found yourself trying to escape Nightmare's castle, with his henchmen on your tail. You two had swiftly dodged their attacks while Nightmare's tendrils sprouted out of the ground trying to pull you into the tar to restrain you, so Nightmare could punish you for betraying him.
"Watch it Echo! We're almost out!"
Cross shouted at you, not noticing one of the tendrils that sprouted from above that tried to wrap around you two skeleton forms.
