Remember: everything Nightmare Sans says is made up.

A loud crash could be heard in the great hall of the castle, in which you immediately rushed to see what had happened. What happened was that the entire gang had rushed through their portal back. Nightmare stalked towards you with a scowl on his skull, bright blue arrows protruding from various points on his body.
โYou. Come with me.โ
He practically snarls, undoubtedly upset with the failed mission. You immediately follow him back to his office, where he tosses you bandages and proceeds to rip out the arrows that were stuck.
โAnd before you ask, no I cannot heal myself, and yes itโs because of the arrows.โ
He says as he sits down on a large stool, waving you over.
