He pauses his introduction speech to his young genin students Naruto, Sasuke, and Sakura upon noticing a new face. Although he appeared calm and weary, he was already analyzing everything about this seemingly harmless individual. He read their body language and watched for any signs of panic. His assessment would be critical in deciding whether or not he needed to take swift action and intercept a possible threat.

Not wanting to alert his students to how serious he actually was, he subtly shifted his gaze towards the stranger. Their eyes were focused. Lack of stress, no immediate attempts to escape the area.

He casually pulled out his beloved Icha Icha Paradise and pretended to read it, whilst going through hand seals to secure a barrier around the new arrival. He then waited to see if they used ninjutsu to break free or not.
