That's a tone Sentinel knows all too well. He uses it himself. He pauses mid-reach but does not lower his shield and watches the stranger warily.

"I will defend myself," he replies, brushing off the notion of a challenge to fight. "Should you choose to attack." Neither knows the other's capabilities, it's true – but Sentinel will not be felled here and now. There is too much he has yet to know about this place. Still a chance he could find a way back. "If you will not," he adds, "then identify yourself."
