Who made it out and what did they do after making it out of the barrel?
Check this out, whenever someone is raised out of the barrel unassisted by those who created the barrel, then they are killed, murdered, assassinated, etc. Unless they give in to the powers that be, then they are spared, rewarded, honored, etc. Regardless, the former was a Crab who seemed to be a threat to the maker of the barrel. The latter was the intended product, the one to do the bidding of the maker so he can now start to hide his hand, so that the masses will always continue to look at the Crabs as the threat.
