Sorry souls

A "warm" welcome

We had been walking for what felt like forever through puzzles, until we finally got to an exit.
Kris looks around and first notices a tree, it doesn't look very healthy and has no leaves. They decided not to question it.

"Soooo... This is where you live, huh?" Susie decided to break the silence.

Frisk looked over at Susie "Yes," she responded "This is where me and my mom live."
Frisk turned around and started walking towards the house. As she did, she walked around the tree, it looked like she was being careful not to step on the leaves. Seeing that made Kris want to do the same, maybe it was important?
We got to the door and Frisk opened it, stepping in and then to the side to let Kris and Susie in. Susie smelled the air, something smelled good and seemed to fill the house with the delicious scent. But something also seemed off to Susie, but, because Susie is Susie, she didn't say anything.

"Do you want a tour of the house?" Frisk asked as the other two looked around the opening hallway "It may not be that big but it's better to know your way around the house than get lost." She said, smiling a little.
"Nah" Susie says before Kris has a chance to answer "I want to know what that smell is." She looks around while sniffing the air.
"Oh, mom's making pie. She said it's a surprise," Frisk says, lowering her voice slightly "but she's only made snail pie, cinnamon pie, or butterscotch pie"
Just as she finishes saying that they all hear an "Oh dear!" Come from the left side of the long hallway along with a rushing of footsteps.

Frisk walks over to the end of the hall with Kris and Susie, then suddenly rushes over to what looks like a kitchen (based on the fridge) Susie notices a bad smell in the air, it kind of smells like... Smoke?

"Oh dear, I knew I shouldn't have started reading while cooking!" A familiar tall figure is trying to fan smoke down as Frisk is trying to drag the fire extinguisher over to what looks like a stove. "Oh, I can take that dear, thank you for bringing it over." She takes the extinguisher from Frisk, or rather the floor, and sprays it at the stove.
She then turns around to see Kris and Susie at the door and looks surprised.
"Oh, I forgot we had guests! I'm terribly sorry for such a smokey welcome, I got distracted reading a book and.. forgot I was cooking." The tall woman smiled sweetly, though she had a small look of embarrassment on her face.

Kris and Susie looked at each other in shock, were they both seeing the same thing? "Mom?" Kris said, looking confused.
"Who, me?" The tall woman asked, pointing at her chest with a confused expression. Kris nodded.
"No dear, I've only just met you, I couldn't be your mother." She responded. "Speaking of 'just meeting', I nearly forgot to introduce myself" She smiled again " My name is Toriel, I'm Frisk's mother"

Susie and Kris were still in shock, but decided to hide it for now.

"I'm Kris, and this is Susie" Kris said, They didn't want to be rude and continue the silence.
