Well, first we have to establish if that's what the crew as a whole intends to do!  If you decide to accept the job instead...killing the client outright is kind of bad for your rep, innit?<br/><br/>IF that's how this is gonna go down, then you decide on what type of plan you came up with before all this started and provide the necessarily detail.  Then the Engagement roll tells us how close to the plan the situation comes.<br/><br/>THEN we worry about individual action rolls, possibly including flashbacks.<br/><br/>UPDATE: and no, I don't think it would be Prowl.  Surprise attack?  Yes.  But you aren't behind him or in a position to sneak up.  He knows you're there.  His gang knows you're there.  And this being Bazzer,<em>who knows you don't like him to begin with</em>?  It possibly isn't that much of a surprise if you try something so direct.
