DP002: Two Degrees of Separation!

"Two Degrees of Seperation" was the first episode of the Diamond and Pearl series. In this episode, Ash was seperated from his Pikachu, due to a tussle with Team Rocket. This episode was also where Ash catches his Starly, and meets Pual, who, when asked if he saw a Pikachu, rudely commented back and asked for a battle with Ash. The match was supposed to be a 3 on 3, but Ash was low on one Pokemon, due to losing PIkachu. Pual notedly reacted harshly towards Ash because of this. Later in the second episode, Pikachu is found my Dawn, a new trainer who starts out with a Piplup.
