Haha! Well, Jink does have the reckless quality ... and also braggart... so he is always looking for a way to up his rep - what better way than taking out notorious Clean Steve! Especially when he and his friends are coming to kill us! (Or, at least, are coming to check out Vanians while we're already there...). I guess Jink has the impression they are coming to get them!
... But ok, let me figure out how surprise works... perhaps instead Jink could try to stick his gun out and demand that Clean Steve & his goons "Freeze!" Then we shall see if talking is possible.. ?
