Mamoru's expression was cold and emotionless as he gazed down at the 'guard' on the floor. When Tharja joined him standing over the man, he regarded her for a moment in curiosity. He realized two things at that point. The first was that she must have been responsible for the acid attack. The second was that she seemed in a considerably better mood now, and Mamoru was not sure just what to make of that. Typically, the discovery that you were involved with someone dangerous was unsettling. Typically, an attack on one's life sent a person into fear, panic, unease-- at the very least, displeasure. Typically, a person didn't know how to fend for themselves in such a situation.

Clearly, Tharja was not your typical girl.

Her skill and cool head were qualities to recognize and admire once he'd had a little more time for their appearances to sink in. For now, it was surprise, mild confusion, and appreciation, though it was only barely evident in his expression.

He looked back down at the attacker.

"I don't think she's kidding. You might want to listen."

Those screams sounded pretty painful. Permanent facial scarring, Mamoru guessed.
