Sakura uses Kero as a model for her art homework. He doesn't like her work, however, and draws over it. During a trip to the museum, Sakura and her class see a boy arguing to fix his dad's painting; then the painting starts to move, and the class ends up outside. Realizing another Clow Card is at hand, Sakura and Tomoyo head to the museum at night and ally with the boy, Yuuki, to capture the card and save the original painting.
Tropes for this episode include:
- Crazy-Prepared: Tomoyo brings the night guard's schedule so that she and Sakura know when it's safe to enter the museum.
- Death Glare: Sakura glares at Kero when talking about how she knows what it's like to have art defaced.
- Failure Montage: Trying to be absolutely quiet when capturing the Silence leads to Sakura, Tomoyo, and Yuuki getting teleported outside multiple times.
- Gender-Blender Name: Yuuki, the "thief" that was trying to fix her dad's paintings. She was covering her hair with a hat, but it falls off once Sakura captures the card. Sakura apologizes to her for addressing her as "Yuuki-kun" (the male suffix) rather than "Yuuki-chan" (the female suffix). In the Nelvana version this was changed to "Alex," for similar reasons.
- Loophole Abuse: Sakura can't capture the card as long as she makes a noise. So she summons the Shadow Card to do the job for her and free Yuuki from the night guard, since shadows don't make any sounds.
- Nerves of Steel: Yuuki doesn't scare easily, when it comes to security guards or puppet shows. Sakura and Tomoyo find it better to ally with her.
- Samus Is a Girl: Yuuki is a girl who was covering her hair while attempting to get the defacing off. Sakura, Tomoyo and Kero only find out at the end.
- Tragic Keepsake: The painting is this for Yuuki, since her father passed away a year ago. It turns out that it's a painting of her.
- Weirdness Censor: Averted. Yuuki has been trying to get rid of the Silence long enough to know something abnormal is going on.
- Wham Shot:
- The real painting that Yuuki wanted to fix; it was a portrait of her with long hair smiling before her dad died.
- At the end of the episode, a strange figure stands on top of the museum, watching Sakura and Tomoyo leave.
