Trivia

 * The fact that Max used to be an astronaut was mentioned again in this episode, the first mention of it being in The Return. It is also mentioned once again how he was supposed to go to the moon with NASA but ended up leaving before he had the chance, though he eventually made it to the moon under different terms.
 * This episode features the least amount of alien changes for Ben with him only transforming once.
 * Many comparisons between Max and Kevin are made within this episode such as how Max was Kevin's age (17) when he met Verdona, and his general personality greatly reflected Kevin's. It is also mentioned that Max had built his car basically from scratch in a similar fashion to Kevin and his respective car. They also fell in love with anodites, Kevin being in love with Gwen and Max being in love with Verdona. (What was different was Kevin met Gwen when he 11 and then met her again at age 16, which is when Kevin start to like Gwen.)
