Betty's pov: So sans thinks that he can "change" me. Ha! He can't! I'm the soul of fear and I can't be a good person! My master taught me that!
(Sans is standing there with his eyes close with his hand on the two slash marks and then he opens his eyes and gets into a battle position and gets ready to change better for good, he throws little bones at Betty and she deflects them and fires her projectiles but sans blocks them with bones and then Betty runs at sans attempting to slash him but sans summons his bone from phase 2 and blocks it with the same face from phase 2 and they hit each other's weapons until sans throws the bone and gets his hate face from phase 3 and fires blasters who runs away from them then he gets a sad face again and pops bones out of the ground and Betty jumps away from them and then he throws more bones at Betty but she dodges them then she runs at sans and attempts to slash him but sans dodges and then sans uses blue magic and throws Betty around until he gets tired and stops)
S: Betty please... you don't need to do this. You can still do good.
B:Good?! Hah! As if! I am the soul of fear! I can never change!
S:Really? Then I will try to do one last thing.
(Sans stops her with blue magic)
B: What are you-
S: Showing you the good times.
(Betty then sees memories from before she betrayed everyone)
