Pokemon Black & White Episode 15 The Battle According to Lenora

After being given a short tour of the Nacrene City Museum, Lenora accepts Ash's challenge, leading him, Cilan, Iris, and Hawes down into the gym's Arena. Lenora sends out her Lillipup, which Iris and Ash find cute, but Cilan reminds them that it is a Gym Battle. Ash sends out Tepig to fight Lillipup, but Lillipup uses Roar to send Tepig back and force Oshawott into the battle. Lenora then recalls Lillipup to send out Watchog, which uses its Mean Look to trap Oshawott in the fight. Oshawott holds his own in the fight for a while before Watchog separates Oshawott from his shell and uses Thunderbolt to defeat him. Ash sends Tepig out once more, and Lenora switches back to Lillipup, and her Lillipup uses Shadow Ball and Take Down to defeat Tepig. After the match, Ash is dejected until Don George tells him not to give up so easily, promising to teach Ash's Pokémon a new move. Meanwhile, Team Rocket infiltrates the museum and steals a meteorite, replacing it with the fake one they received earlier from Pierce.
