Two Degrees of Seperation was the second episode of the Diamond and Pearl series. In this episode, Ash was separated from his Pikachu, due to a battle against Team Rocket. This episode was also where Ash catches his Starly using his Aipom. Also the first episode where meets Paul, 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 Pokémon, due to losing Pikachu. Paul notedly reacted harshly towards Ash because of this. Later, in this episode, Pikachu is found by Dawn, a new trainer who starts out with a Piplup.
When Carnivine comes out of its Poké ball, it greets James the same way his Victreebel used to: by chomping on his head.
When Dawn calls Rowan, both of the areas they are in are identical on the video even when they are in different areas.
James: "There you are you rascals."
Jessie: "Oooo, what's in there huh?"
Meowth: "Something a lot older than me."
James pulls out bottlecaps from the box.
James: "It's my very first bottlecap collection. I've had it since I was a toddling tot of two. To brush them against my cheek. WOW! I can not believe you've been hiding in here all this time."
Jessie: "A Poké ball. Yours as well?"
James: "And how. The very Pokémon I used to play with when we came to Sinnoh. Come on out Carnivine."
A Carnivine comes out and bite James' head.
James: "You see, Victreebel's not the only Pokémon who likes to take a nip at my noggin."
Jessie: "And that is a good thing?"
Meowth: "Wow, sounds like the green galoot's really happy to see ya."
