Emile traversed Route 1 with Ottawa, attempting to catch as many Lillipup as possible to take advantage of their Pickup Abilities to potentially gather many rare items. Lillipup, at Level 2, was the first one he encountered; Ottawa weakened him to 5 HP with one Tackle attack and he retaliated with Leer. Emile then threw one Poké Ball, succeeding in catching it.
After catching five Lillipup, he checked each of their stats and was pleased to see that Lillipup had the Pickup Ability. He healed him shortly afterward at the Accumula Pokémon Center.
Emile started the new episode off by recapping on his amazing luck in gaining four out of five Lillipup that had Pickup, among other things. He then noticed that Lillipup and Lillipap had already picked up items with their Abilities, and retrieved from them a Super Potion and Potion, respectively.
Shortly afterward, he heard from an NPC that he and his Pokémon looked alike, and Emile apologized to Ottawa for feeling humiliated from the comparison, though then he mused on how his hair sort of resembled Lillipup's, but decided that he was insulted either way.
Shortly after depositing Lillipoop in the PC, Emile reviewed his party and, upon seeing that Lillipup was holding another item, praised him for carrying his own weight before taking the Potion from him.
After defeating Striaton City Gym Leader Cilan, Emile checked his team and collected another Potion from Lillipup.
