I think Crocus stated he didn't leave Laboon in all those years iirc.
Got up to Zoro's fight against the 100 bounty hunters from Whisky Peak. It's interesting that Vivi states that now she can see, assuming Zoro is the captain, why he's worth 30 millions beli... and that's after defeating the bulk of the bounty hunters and not even getting to the ranked workers. Maybe this sheds light on the pretty big increase the SWs get after going through an island, if Zoro not even outright defeating all of them is already enough for her to believe the 30 millions beli (and thus above Arlong) already does justice ro what Zoro had displayed.
... but then I remembered that in Captain Kuro's arc, Jango stated that Kuro's "silent step" could allow him to kill 50 assassins pretty quickly, so maybe Zoro's feat doesn't scale as impressive and Vivi was just off on what 30,000,000 really indicates.
Btw, switched to Viz's Black and White version instead of the color ones, since the colored scans were getting its speech bubbles pretty small sized on my smartphone.
