Sid's Revenge / Roller Coaster - S3-E8
Trivia: There are two versions of this episode. Originally, the closing credits appeared over the ending scene with Eugene going around and around in the roller coaster. When Nickelodeon switched to its "squeezed" credits format, a second version was created with the credits removed from that scene, and a new set of credits (over the "normal" credits background) added to the end. (This was later done with "Principal Simmons" as well.)
Answer: No, he did not. He is seen getting off the bus with a suitcase, so he must have not been home for a few days so there is no way he could have known.
