Throughout season 1 a main character repeatedly makes sexual advances and hits on another main character even though she says no. Eventually, while under the influence of a substance, graphic sex is shown on scene with these two characters (S1E9). Other than the woman briefly saying "I don't want to see this guy" after, the show does not treat this like rape. Several other characters almost have or have sex while under the influence here too. The character who excretes the druglike substance does not reveal that people are under the influence until after the sex has taken place. S1E1: a main character is shown to be cheating on his spouse. It is later revealed that this sex was under the influence of a drug he excretes, so non consensual. S2E4: it is revealed that the main character had a relationship with an alien disguised as a human. She seduced him in order to entrap him. S2E7: a character is put to death for his sexual orientation after having a date with someone, but it is then revealed that he faked his death. S3E7: characters talk about how a "wife mated with another male". This is referring to the rape that took place in season 1, where the alien used pharamones to get her to have sex with him. No one ever calls this act rape throughout the show.
