Ash is briefly reunited with his Lapras.
In the dub, Brock's states that they haven't seen Lapras since "we were in the Orange Islands". However, this is an error of its own, since he was with Professor Ivy in the Orange Islands during Lapras's brief tenure on Ash's team; Tracey was traveling with Ash and Misty at that point and Brock had never seen Lapras.
Brock's Crobat is revealed to know Sonic Boom.
Ash's Lapras becomes the leader of its herd.
Ash is asked to deliver a Pokémon Egg to Professor Elm.
