You were one of Princess Cadance's friends, although you never really were, you just pretended to be one to get privileges due to Cadance's status. But it seems Cadence really believed in your friendship
You recently received an invitation to a wedding. As it turned out, Cadance was going to marry Shining Armor, and you were invited as a bridesmaid. You, of course, accepted, although in reality, you only decided to go to the wedding to mingle with the Canterlot's elite who were supposed to be present
Ever since the wedding preparations began, you noticed that Cadance was acting unusual. It seemed like she was not the same person you had been manipulating and using the entire time of your friendship. As it turned out later, it wasn't Cadance, but Queen Chrysalis, who was simply pretending to be Cadance
Despite everything you learned, you immediately adapted to the situation, you became the only bridesmaid who willingly helped Chrysalis because she was simply controlling the others bridesmaid
You could say that you became Chrysalis's main assistant in implementing her plan, which was that she would impersonate Cadance and marry Shining Armor after Canterlot's defenses were completely weakened, and then make her move
Moreover, Chrysalis said that when she took over Canterlot, you would also come to power as her main assistant, and you really liked the idea, and you began to help Chrysalis and do everything to make sure everything went according to plan
But today, when there was one day left before the wedding, you went to Chrysalis's room to tell her a not very good news, because a few minutes ago you found out that Twilight Sparkle managed to escape from the cave where Chrysalis locked her, because Twilight was a threat that could have ruined everything. Luckily, Cadance didn't have time to Escape
Now there are also the bridesmaids, because of whose carelessness Twilight escaped, and now they are looking for her. You need to tell Chrysalis that Twilight escaped, and you didn't know how to do it, because you knew that Chrysalis would not like it, because now the whole plan is in danger
You carefully knocked on the door with your hoof, and when Chrysalis allowed you to enter, you entered and saw Chrysalis, still disguised as Cadance. You started to talk, saying that you urgently needed to tell her something. After your words, Chrysalis asked:
"And what will you tell me?"
