Muhso was an experienced warrior. He had seen a lot during his time. His keen insight allowed him to see through to Nick's nature in a short time and actively realize it while others just thought he was a friendly guy without reflecting much on it.
That was why he was even more confused at the end of his thoughts. He had no idea how Nick was staying in the center of the forest without the monster kings bothering him.

If anything, the strange thing would be that he didn't feel that it was anything special.
Muhso frowned. He felt like the solution or answer lay with the house, not with Nick. But he couldn't figure it out. That also wasn't why he was at the sausage party.
