This scan is from Wolverine Vol. 2 Issue 1. I just recently reread this particular issue and I vividly remembered this exact scene. I just love this dude's reaction after figuring out that what he thought was an easy kill, was in fact nothing of the sort. But don't you worry yourself too much, mind-boggled pirate guy, it will all be over before you know it, as Wolverine goes on to do what he does best. Remember, "Come at Wolverine with a sword, and he'll meet you with a sword."
