Hmm an interesting theory especially on the element of friendship and how Twilight's ascension could be the element of friendship accepting her as a host. Do you know perhaps if there is a Greek legend or so on it? The reason is because the show uses a lot of references from the Greek mythology on the show and that theory of yours can have a stronger case of being true. Finally, I would like to ask about the role of Twilight's friends in this if you will? It is only to provide a means for your theory to be stronger.
