Dawn begins to suffer a lack of confidence after her recent Pokémon Contest losses.
Brock's Happiny learns Secret Power and is also revealed to know Pound.
The English dub title of this episode is derived from the saying "Thanks for the memories."
This episode has a similar theme to The Lotad Lowdown (2003). Three sisters are introduced, Brock falls in love with the two older sisters, and the youngest sister is in love with Brock, resulting in the younger sister becoming jealous and angry at Brock when he doesn't pay attention to her.
Despite learning it in this episode, Brock's Happiny would not be seen using Secret Power again throughout the remainder of the series.
