"go right ahead... be honest chara.. i don't want you to beg.. i want you to be happy.. if you're happy. then.. well.. i think that would be good for the both of us" he smiled and chuckled a little bit "if you're happy.... well.. it would be great for you" sans was being genuine. he didn't want to learn that the only thing that made her happy was hurting and killing..... he... would have to get rid of her.. sans really didn't want that. As mean as she was.. it was probably because of something.. He knew there was a reason.. if she could open up he wouldn't need to get rid of her. He was going to try his hardest to help her too! even if frisk couldn't.. he had to.. he just had too once.
