Twilight was abandoned by her friends and even her teacher in favour of a pony they had just met; Princess Mi Amore Cadenza. After it was all over, they apologized, and Twilight said it was alright, but was it really? Could she really just forgive them so easily for flat out abandoning her and not even trying to find her when she went missing? Dash doesn't think so, and she's going to get the real story if it's the last thing she does, even if it means her own secret coming out.
Look, I'm gonna be honest; you know those really dumb, melodramatic soap operas? This is basically that. Call it a guilty pleasure of mine, but sometimes I like to indulge myself.
