"Well, According to what we have just witnessed today, that is most certainly untrue." He growled lowly, "She is a threat to the MMO, and everyone in it." I stayed silent, I couldn't believe that she was actually alive, all this time, I could have completed that lousy task and been done with this ordeal. "Well, what do you want me to do about it, Asgore?!" "Find her, and kill her." He said harshly. "You're one of the best fighters in the Mafia, Sans. Don't disappoint me this time." "Yes sir." "Actually.." he stood up, a smirk on his face. "I have a better idea."
