Chrysalis disguised as an unicorn was just sitting in ponyville park. She was not feeding on the abundant love around her. She wasn't attacking ponies and encasing them in cocoons, in fact all that she was doing was watching the ponies go on about their business on this Hearts and Hooves day. Starlight knew that she was up to something but she hadn't moved or done anything other then watch pony couples and it was driving Starlight crazy.
