If you're asking how he knew where Graves would shoot so he could put the blood pack there, the answer is simple. Shut up. He's Clark Parker. Best P.I. in town and all that jazz. Also if you're asking why he has his coat on when he punches Graves, but not in the next panel, it's because he took it off to reveal what was under his shirt. It is in no way due to my lack of attention being paid at the time of creating this comic...yeah, that sounds convincing...anyway, until Monday.
