Kristoff was attempting to not be increasingly unsettled by how nice this guy was being, but his long-solidified habits of casual distrust were making it difficult. He could help himself to whatever he needed? He could have bacon, eggs, and coffee? There had to be some kind of catch, something bigger going on here, and his wariness was once again on his face as he followed Nelson into the kitchen.

"Yes... Uh. Sure. Please," he answered in spite of his small worries on the matter. He wasn't going to reject the offer outright. He was hungry, after all. He lingered in the kitchen doorway, looking around in an attempt to decipher all of the unfamiliar items. He almost missed the next question, and quite nearly winced at it. Small talk. "I'm, uh... I'm from the mountains. Well, from around Arendelle."

Because there were lots of mountains in the world, but they weren't his mountains.
