Though his disdain at Shin's joke was quite apparent, the skeletal figure deemed it reasonable enough for him to complete his job without a hitch. The mud child hadn't said much, but one could not expect something with no real trachea or mouth to really speak much. Would you? "Great, then we're in agreement. I kill the kid, because he's over there harming himself. You get your information, I get paid. And then we all go home, lay a woman or man of your preference, and nobody but the mud baby gets hurt. That sounds like a full day's schedule to me. I intend to be back home before breakfast tomorrow." 

Shin tilted his head towards the mudman, raising his left hand upwards. Aiming the but of the staff directly at the center of his head. "Now, about you. Normally I'd say 'You have one last chance before I attack!' However, you're probably not the reasonable sort. So I'll let my weapon do the talking for me." 

Without the slightest movement, or rather, without any movement on Shin's part. The staff began to grow, extending forward so quick that normal men would be run down before they could even react. The staff grew towards Jynx's head with cruel intent, Shin wanted to end this as quickly and quietly as possible. Honestly, he's trying to take it's head off in one strike. That doesn't mean that he won't resort to incredible violence, it's just preferred that it end quickly.
