Toriel sighed, staring at the two. Sans glared back at her, holding Frisk's hand.
It had been three days since the birth, Aliza now peacefully sleeping in Asriel's old cradle. Now, they had to talk.
"What you two did was reckless." She started. "You could've endangered Frisk and Aliza both."
He tensed. Magic started to him in the air, ready to whisk Frisk, Sans, and Aliza all away.
"But, I believe it is partially my fault." She sighed. "I raised your fears."
Frisk sighed. "It wasn't your fault Mom. Sans and I...we weren't sure how people would react."
"It's alright." Toriel sighed. "What's done is done. And I got a grandchild out of it." She smiled at the porch, where Mettaton and Papyrus were gently rocking the cradle for Aliza to sleep.
"And there is something else we need to deal with." Sans said. He reached into his pocket, pulling something sparkly out. "I was waiting for Frisk's graduation but...no time like the present?"
Frisk stared at him as he turned to her. "Frisk Dreemurr, mother of my baby, would you make me that happiest monster born?"
The ring was beautiful- a heart was formed from red and blue gemstones. She gasped, nodding excitedly.
"Yes."
