Since Juliets last word were "It worked" I thought about that deceased people somehow end up in the alternate timeline. I posted a blog entry about Deceased people end up in alternate Timeline. I swear I was spoiler free.
Now this theory became mainly true except of my thought was that it had something to do with the donkey wheel and that it is no afterlife or something like that. I expected an better ending though.
What do you thing about my former theory with the fact that it become true. I think many had this - in german we say "Gedankenexperiment" - about decased people end up in alternate timeline but rejected that thought as ridiculous.
