Here are some situations where Darien's feelings might be interpreted as jealousy:
* Early in the series: Darien seems a bit possessive of Usagi, sometimes getting upset when she interacts with other boys, but this could be interpreted as concern or just being used to her being his "little sister."
* Episodes with Other Love Interests: There are episodes where Usagi develops crushes on other guys, like the handsome boy in the "Fashion Show" episode, but Darien doesn't seem to exhibit jealousy directly. Instead, he usually relies on his charm and presence to win Usagi back.
* His "Dark" Transformation: In *Sailor Moon R*, when Darien is temporarily possessed by the Dark Kingdom, he acts cold and distant towards Usagi. This could be seen as him rejecting Usagi, but it's more about the possession than jealousy.
Ultimately, jealousy isn't a prominent trait in Darien's character. He's confident in his love for Usagi and tends to deal with potential rivals with a sense of humor and confidence.
Instead of outright jealousy, you might be thinking about scenes where Darien experiences:
* Concern: When Usagi is in danger, he's incredibly worried for her safety.
* Frustration: Sometimes he feels frustrated when Usagi doesn't understand his feelings or acts impulsively.
* Competitiveness: While not always jealousy, he sometimes gets competitive with other guys who show interest in Usagi, particularly in the early seasons.
