Poor Trixie. It’s more that her own insecurity makes her feel threatened (and therefore jealous) she sees her two partners being affectionate on their own. If deep down you feel you can’t be loved, what gesture of love can someone make that would penetrate it?
 
For the moment, they should totally smother her in adorable kisses. And maybe she’ll see she shouldn’t feel threatened when she notices that when it’s her and Pinkie Soarin doesn’t mind and that when it’s her and Soarin Pinkie doesn’t mind. But, that’ll only help in the short run.
 
This is supposed to be a funny thing but I can only think of how much it can’t be easy being Trixie. She probably really needs therapy or something…

I think, Trixie wants the affection of the pink one.

“But Trixie wants to touch the big,strong,blue,wonderbolt too…”
