In other words, could certain questions finally get answed , and certain theroies be put to rest. Well, with any kind of closuer on a franchise, the finale always seems to (at most times) open the doors to allow the writers to get a lot of stuff out of their system for themselves and for at most, the fans.
But will the final season of MLP : FIM do that as well? Here I talk about what could be finally addressed, if that is the case.
Now one of the first things that they (the writers) could finally address, is the whole Spike x Rarity situation. What I mean is, that if the writers choose to do so (IMO I believe they will), this will finally be addressed, and the outcome will be one that is a positive one, and yet be one that not a lot of the brony/pegasister community will agree on. And what the outcome will be, Spike and Rarity together.
You may ask "How?" Well, it's quite simple, if you look at the fact, that they've been teasing this since Eps. 1,
