Okay, I don't think trying to defeat Memon with violence is gonna accomplish much, and since we know xey just really miss how good the old times were...
*Shows Memon all the happy memories Sans and Papyrus made while living in the underground, memories of the fun they had, the people they befriended, things they've accomplished, all that stuff*
(And Sans unknowingly managed to save his brother from being tortured! Makes sense, given how often Papyrus has to save him. In case you didn't realise, the illusions and attacks Memon put on Papyrus were tied to xeir mental state. As xey were placated by Sans, their abilities gradually let up, which made it easier for the other Darkners to get rid of them. And Memon can speak in Sans' font because of how closely tied they are to each other. I think Scarffet could also speak Papyrus if he wanted to, he just doesn't most of the time. Anyway, I hope you enjoyed this!)
