[Peggy may barely know Frisk, but she's not going to let a child suffer in silence and alone like this. Carefully, she walks over to Frisk, and kneels by their side, very conscious not to touch them until she's being told it's okay.]

Are you hungry? We have plenty of food.

[Peggy slides her backpack off her back, opening it and pulling out rations for Frisk, would they want them. All that she knows is that they lost their mother, Toriel.]

Alternatively, if you just want a hug, I'm happy to provide. Steve will tell you, I'm very good at them. [She smiles, hoping she'll get the child to, at least, look at her. She is no replacement for their mother, but she can try her very best.]
