I actually like this episode. Ash put his own pokémon before himself and tried to get pikachu to get in to its pokeball. Pikachu rather stay out to keep Ash warm. Plus his other pokemon came back out as well. It was an emotional scene right there. When I think about, it doesn’t really surprised me that Ash didn’t get sick with a bad cold from being in that cold cave all night long. Plus it kind of serves him right to go up a harsh mountain path, getting lost while chasing after Pikachu, and nearly freezing in a cave. While on the other hand, Brock and Misty, tried and failed to convince Ash to go back down the mountain and take the other road instead. They found an underground hot spring and warmed up comfortably.
