They do draw many. Too many in fact even in situations where it wouldn't make sense to. Which is why I said it doesn't mean anything. You have several examples in the current chapter alone. You have panels with Ussop, Marco, Miss Buckingham all sweating. Take a look at it and Zoro smirking has nothing to do with S-Hawk. He had no trouble with Zoro as far as I can tell he knocked him back just fine. If anything he was surprised more so than afraid.
This whole thing of S-Hawk being afraid of Zoro came about because of something the spoiler providers said. As usual you guys jump at the first chance to wank Zoro. Even before the chapter comes out. We all know the real reason you guys are push so hard on this idea. It's because you guys were wrong once again.
