Shakespeare? That's really cool, though my favorite literature is mostly centered around history. Hi, my name is Damien Thorn, formerly of Chicago. Or.. Rome, born there. But I've lived in the UK and Chicago before Lawrence.
As to the island. I'd want salt, a good knife (I'd say ballistic blade, but that only gets one use) or a sword, and a lighter. I'd want a limitless supply of noodle soup.
I'd definitely want Prue there.. my girlfriend. Not sure who else. Phoebe, most likely, since I know that sisters or any family should never be apart.
