A year later, the Royal Guard celebrated removal of those antimagic bracelets. Sans didn't miss them.
Humans weren't entirely forgiving of the dead children incident, as Sans found out when paying for a wedding venue with Toriel. Sans was sure he was paying double as a child killing fee. He was a tad worried complaining wouldn't help him, so let it go.
When he and Toriel finally got married, all the MT. Ebott monsters came, even a reluctant Asgore, who was sitting beside Frisk who insisted they didn't want to be in the wedding party. Flowey also didn't want to be in the wedding party, so was sitting beside Papyrus. Sans wished a glare from Omori didn't come with his wedding guests, but he learned that Omori was rather protective of Frisk, despite not being related, his sister he understood, but Frisk was a surprising addition to Omori's chosen family.
After the wedding, Omori walked to Sans. "Sup?" Omori still glared at him, "I am warning you now. Touch Frisk and you will regret the day you were born." Sans realized no one was around, "Shame people think you're shy." Omori just smiled at Sans. "Goodbye." Sans knew he was going to have his every move regarding Frisk judged by many humans. They still were reluctant with human/monster arrangements.
