This is the first episode in which Tommy and Kimberly explicitly show romantic interest. Kim previously displayed attraction to Tommy during the Green With Evil five-parter and while it seemed he was attracted to her as well those feelings were overshadowed by Rita's evil spell. They once again showed subtle romantic feelings during the episode Calamity Kimberly but neither actually expressed their feelings openly to the other.
When Tommy told Zordon that he didn't touch the green candle, and Zordon replies to Tommy that he did when he worked for Rita, he might have forgotten about it after Jason broke Rita's spell over Tommy.
