Well, to me the suggestion would be just have a comic about Trixie being Trixie instead of just following the boring idea of her and Twi's rivalry. I guess I should be happy at least you aren't shipping them (yet, if you do there's no chance for this).
But meh, the dark and 'aggressive' stallion that randomly appeared? He's pretty fucking boring. Saw him and he's so cliche I just rolled my eyes and couldn't be bothered.
