Twilight has had a liking for Flash ever since her first visit to the human world, and while their relationship has had a few stumbles here and there, things have overall gone well for them. However, one day, she comes to realise something important about the very notion of them being together.
As such, she decides to see him again, and say something that, perhaps, she should have realised from the start.
Part of the Rainbooms/Dazzlings/Shadowbolts storyline.
