Uncertainty

As Argan watched the man's receding back, he hesitated for a bit before eventually, he moved his legs and followed him from behind. However, he still kept his guard up, watching the tall figure warily as they walked down the open hallways towards the inner part of the academy building.

Argan had sharpened his senses throughout their journey. He was ready to bail if he were to sense even the slightest bit of danger from his surroundings. He also made sure to keep a lookout for any ambush since he didn't know what this man was planning and neither did he know the other party's identity. However, he didn't seem to mean any harm at least for now.
