With all of the Wizard of Oz red herrings this episode I cant help but wonder if maybe Whale’s brother is the Wizard of Oz. We know that Whale trying to bring his brother back happens after Dorothy goes back to Kansas – hence after the Wizard takes off in the hot air balloon (movie – not sure how the book goes as I haven’t read it). What if he died trying to get back to his home land. I don’t mean Kansas like Dorothy, but his home land with Franky. We know the writers like to change the stories a little, so perhaps he wasn’t from the same land as Dorothy, but they were both just looking to get back to their particular homes.
Just a fun thought – perhaps the Wizard of Oz hints weren’t directed at the character we thought =)
