Troublemaker.Jagged Stone decides to guest star in a live-recording television show, Fill My Shoes, where a person is taking part in another person's job, and the show featuring him is taking place at Marinette's parents' bakery. Wanting to impress Jagged, Penny is running back and forward until everything goes out of control. With pressure from all sides, Penny ends up getting a nervous breakdown, needing a break from everyone. Hawk Moth takes advantage of the pressure on Penny and akumatizes her as "Troublemaker", a villain capable of switching from tangible to intangible, making a big mess, and urges to get back at those who shunned her. Throughout the commotion, the discovery of Adrien's photos in Marinette's room has Marinette in a panic, even when Cat Noir/Adrien tries to look at his own pictures. Not ready to tell how she feels, Marinette later manages to convince Adrien that she is just a fashion fan and he invites her to one of his photoshoots.
