With her mind still in a fight-or-flight mode, the blonde whipped towards her back and finally took notice of the raven-haired stranger. With the looted knife still in her grip, she immediately assumed a defensive stance. Not even his nervous laughter and on-the-spot excuse made her drop her guard, given what she had just gone through. She didn't know who he was and why he was there and she wasn't about to take his words on face value, especially with the possibility that he had seen what she had done. "Right..." she murmured and glared at him as he stood up and corrected his posture. "And I assume you just tripped to this particular spot, at this particular moment?" Tightening her grip on the knife, the blonde cautiously moved closer to him, knife still within reach. "Did you see it?" she asked in a straightforward manner, having a sinking feeling the raven-haired stranger knew what she meant.
