I know Ash got sick with Tracy in " The Stun Spore Detour" in season 2. Did he get sick another time? If so, please list the episode's name and season. Please help me! Thank you!
Well after perusing countless websites for around 45 minutes I can tell you that "The Stun Spore Detour" is the only episode Ash has ever been sick in.
Sorry I couldn't find anything else for you.
