The teenage beastman's statement was met by an expression of bafflement, as much as could be depicted by the low emotional range that Mougin's face possessed. The confusion was plain on his face, nonetheless.
[color=007236][b]"No, I am not in possession of your back..."[/b][/color] He said in befuddlement.
If a 'back' could be said to belong to anyone, then surely one's back would be in the possession of one's self. A human witticism, perhaps? If so, the meaning eluded him at the current moment. In addition to that, the youth made mention of 'kicking their asses'... If this beastman wished to fight the 3 other youths across the street then this would indeed be a sound tactical decision. One's behind was usually a weak point, after all, and attacks from that direction were difficult to defend against.

[color=007236][b][i]Ah,[/i][/b][/color] Mougin whispered, as he was hit with a sudden burst of enlightenment. This youth had expressed his desire to strike his enemies from the back - therefore, when he asked Mougin if he 'got his back', he was in fact asking him to ensure that his own tactic wasn't used against him. Mougin nodded to himself, content with his reasoning, but tilted his head as he continued thinking. Why had this youth asked him this? Surely it would be wiser to pick someone more familiar to themselves to protect them. He mulled it over for a moment or two, but couldn't come up with a satisfactory answer. This wasn't a situation he had encountered in his life. If so, Mougin could only ask one question.

Well, it probably wouldn't hurt to ask, right?
