Fluttershy

Love triangle

You could make some kind of joke chapter, that instead of one of the girls, he will chose a sandwich that has been in the kitchen for a few weeks, just putting it out there

Sorry to say this, but f**k you fifty shades if yellow.(i pick twilight)

Twilight has my vote.

I think it should be fluttershy but you can choose who it is yourself it is your story after all.

I would say Twilight, but Fluttershy connects with Anon as well. Both..maybe? but seriously I would say Twilight. Perhaps some jealousy to see how they feel about the matter, if he was to chose one over the other.

Fluttershy. Reasons: because f*ck purple smart (Twilight Sparkle is still best pony!)
