"Are you back again?"
Grillby had been taking in the menu sign when he saw the young hero standing outside. They had a couple of new bandages, and the tutu was torn in one place. They'd seen something, and Grillby had an idea of what it was. Sans and Undyne were standing behind the child.
"If you don't mind, Grillby." Sans grinned, patting Frisk's shoulder. "Undyne's crashing at our place."
"Frisk and I had the most epic cooking class!" Undyne shook her fists with excitement at the very thought of it. "We totally mashed those tomatoes against the wall and turned up the heat! It got hot!"
"So hot it burned the house down," Sans finished simply.
There was a silence as those words settled over the group, and Grillby just opened the door a little wider in response.
Frisk excitedly ran inside, eager to escape the cold and into the warmth of the restaurant.
Undyne ran back to Papyrus, yelling something about a totally awesome sleepover, while Sans held back and thanked Grillby once again, saying that he would pay back that tab eventually.
"I'm sure you will," Grillby replied, the joking tone giving away how he felt about it.
Sans waved it off and followed Undyne and Papyrus, who were already talking about all the movies they were going to watch and how they were going to stay up until midnight.
Grillby closed and locked the door behind himself, finding that Frisk was already looking for the broom.
"You don't need to clean up tonight," Grillby absently ruffled the child's hair, and smiled. "You're not going to cook either, after what I hear you did to Undyne's house."
The child looked a little flustered and embarrassed, before going into the kitchen to get another class of water. Grillby followed, asking if they wanted anything for their journey ahead tomorrow. They shook their head in response, showing their spoils from the day. One was a crumpled ticket for a concert, another was a small pile of gold. Then there was the matter of the food – a box of something labelled "Temmie Flaeks", a partially melted Nice Cream, and something that they carefully unwrapped from a napkin – a delectable looking slice of pie.
This child was fine, he considered, although he wondered if he kept a lunchbox of some sort around the place.
…What was he thinking?
The next morning came with Grillby going downstairs, only to walk in the kitchen and find the child atop the counter and crawling up towards the cabinets, reaching towards the oatmeal. Instantly alarmed, he ran forward, ready to catch either the oatmeal when they let go, or the child when they released their grip on the cabinet.
Luckily, neither happened. Frisk allowed themselves to be placed on the floor gently, and Grillby to prepare another dose of oatmeal for their journey ahead.
"Are you going to the boat?" Frisk nodded in response to his question, and when they were done and all packed up, he left with them, personally seeing the child safely to the boat, despite the fact none of Snowdin's residents any longer had a bone to pick with the young human.
Papyrus and Undyne excitedly waved from the doorstep, where they had been making snowballs, while the bunny children hopped excitedly by towards the pine tree in the center square.
While they descended the steps, Grillby found himself wishing that the child would come back again that night, safe. However, they were going very far into the Underground this time, and there was a chance that they might not return.
"Tra la la," the River Person began. "The man who wears his passion on his body might fall victim to it."
Frisk boarded the boat with minimal difficulty, and Grillby gave a small wave when it departed, staying on the shore until it was gone, and he walked back, finding Sans patiently waiting outside the door.
"That River Person is a strange character," Grillby commented while opening the door for them both.
"Heheh. You think? What'd they say to you?"
Grillby chose to not answer that question.
