While staying at Cynthia's villa, Ash and co. meet her neighbor, a boy named Chris. It turns out that Chris's Cubchoo has gone missing so the gang tries to help him find it. Especially Cilan, for whom it is now Detective Time!
This episode contains examples of the following tropes:
- Corner of Woe: Cilan goes into one after Iris calls him a pain for not really solving the mystery
- Designated Victim: They have to help a Cubchoo again?!
- Internal Homage: To Brock, again. Dawn mentions that Cilan's eccenric behavior is similar to Brock's eccentric behavior with pretty girls.
