“Carved from bone, the fish hook is an artisanal symbol of Polynesian culture when worn by a native Hawaiian. When worn by a haole like Hungate, it is perhaps a symbol of either dudeliness or douchiness.”— Moby-Duck, Donovan Hohn
“Rory is supposed to be dead. After all, he was dead or dying before he was erased from existence. However, Amy is some sort of reality warper(possibly due to the crack) and she brought him back. Now, the universe keeps trying to right itself, hence the reason Rory keeps dying. Amy keeps warping reality to cancel this. Eventually, this will start having really bad effects on the universe and Amy will have to accept the loss and let Rory die for good in order to prevent the end of the world as we know it.
This could also explain why the TARDIS sensors can’t figure out if Amy is pregnant or not. She is pregnant with Rory’s child, but Rory is supposed to be dead, so the baby both does and doesn’t exist.”—
