I really hadn't expected Magellan to die when he did. It's almost sad that that's all I can really say at the moment. He lost sight of what he was meant to be doing and focused on converting the natives to Christianity! He might have made it to the spice islands if he hadn't gotten so sidetracked.
There were parts of this book I found really disturbing: the idea of punishment was a bit too much most of the time. That's the one that sticks out the most. I think that was discussed after one of the men got caught with a cabin boy (creepy image, that). Such things were often ignored, but Magellan didn't do so (for some reason) and punished the man.
