This episode was great! It deals with Cory thinking he has some deadly illness but instead finding out he has hypochondria, but on the more dramatic side, Alan finds that he doesn't have faith in Eric entering the real world.
The hypochondria plot was hilarious! Some of Cory's little one-liners were classic! This episode was very well written. I loved the ending as well. Cory "wasn't feeling well" and asked Topanga to hold his hand until he fell asleep. It was one of the many examples of how Cory and Topanga (a long with real life married couples) can have their silly, little spats but at the end of the day, still show love and affection for each other.
All in all, great episode.
