Sean borrowed a couple of Pokémon from his father and showed it to his friends, Mick and Glenn. Glenn took one and battled Sean, while Mick was left out. Glenn quickly had Patrat attack Blitzle and both were left exhausted. Glenn demanded more Pokémon, so Sean came with Seismitoad and Scolipede, both which Glenn used against Mick, who borrowed Krokorok and Pikachu. After the battle, Sean was furious Glenn was careless, for the Pokémon were actually borrowed from his father and are exhausted. Glenn admitted this and apologised to Sean and Mick, then all three watched as Ash battled Krokorok.
Sean borrowed Scolipede from his father so that Glenn could use it in a double battle against Mick. Glenn used it to battle Pikachu despite what Sean had recommended and it was quickly defeated. Sean was upset that Seismitoad got hurt but it was able to heal thanks to Cilan's special food.
Sean borrowed Seismitoad from his father so that Glenn could use it in a double battle against Nick. Sean did tell Seismitoad to block Pikachu's Thunderbolt because it was part Ground-type when Glenn had planned to have Scolipede use a counter attack. He tried to tell Glenn to use it against Pikachu but he would not listen which cost him the battle. Sean was upset that Seismitoad got hurt but it was able to heal thanks to Cilan's special food.
