Rusty could feel a sudden anger like feeling toward Acacia, maybe the fact that her words and personality now were ticking him off? But he wasn't going to start anything, not here on the train that is. Not with the Typhlos running loose. "Well then, Acacia.. I should let you know... Even if you think that you can do things alone, even for the protection of that boy. Or I for the protection of this girl. Do you really think that coming to a conclusion of such aggravation will lead me into a duel?" His ears flicked a bit, his head tilted as if taunting the old soul. "I suggest you watch yourself and have manners. Or things will get gruesome in a matter of seconds.." he bared his canine fangs at her, clearly annoyed by such words.<br/><br/>Although Rusty was one to not get aggravated much, Acacia was one to pull his strings. That alone, he hated. But he knew that he could not fight on this train. Not when it's cold outside and with many people aboard, and the Typhlos loose as well. It could end in a bloody mess if not careful. But Rusty was just stating facts.
