Board Thread:Legitimate Canon Questions/@comment-108.249.140.237-20150404103145/@comment-13965604-20150514130459

The question was 'why do you think the nogitsune chose to possess Stiles?' And not 'why did the show runners decide to have the nogitsune possess Stiles?' It's entirely a speculative question from the get go. If it were the 2nd question we likely never would've seen it unless we went over to the canon questions forum, because Paul probably would've said something similar to what you did instead of transferring it over here.

If you don't care for speculation, I think these forums might not be the place you want to be. Because a lot of it is speculation.
