Several episodes from now, Spike will lose it and go on a shooting spree.
I really want to see him stop getting kicked around. I seriously want to see him go... well, not 'Secret of my Excess' berserk, but enough downright pissed that he finally gets EVERYPONY'S attention, Celestia and Luna included, and just give them a piece of his mind.
Please, for the love of Celestia, no more Spike episodes. Just, no. By the time "Spike at your Service" happened, I wanted to slap the writer(s) responsible. Please, please, please, no more Spike. Do an Applejack epp, or more Rarity, or even more Pinkie Pie. Do one about the background ponies, for heaven's sake![/rant]
To clarify, I don't dislike Spike, or think he's a bad character, I just hate how much focus he gets competed to some of the Mane Six (like Rarity and Applejack, as stated above). I realize there are legitimate reasons for, say, Applejack's lack of episodes (it's hard to do something meaningful with a character when she's already exactly where she wants to be), but I've had enough Spike to last me at least half a season, thanks.
