your dad was a CEO of a secret facility for experimenting on monsters but you don't like it

they see you walk near the cell Sans: oh great another one…what kind of WONDERFUL test do we have today? he askes in a sarcastic tone

Papyrus: looks at you brother she seems harmless…

you see they have cracks on there bones and sans looks exhausted

Sans: so? What kind of torture do we have to endure today…
