Worthy of note: one of the main characters is shown frequently making sexual/romantic advances towards women, including one woman who displays obvious unhappiness about it. The most suggestive of his comments occurs in a scene in the first episode, directly after they first meet, the woman states that they have a particle barrier which they can activate for protection and he replies 'girl, you've already activated my-' before being cut off by another character. Beyond this, their interactions stretch to the male character making comments regarding things like dates, often insinuating that the female character has a crush on him. The narrative never explicitly addresses this dynamic, beyond showing the female character talking to another female character about her displeasure with his behaviour (some interpret this as an expression of jealousy rather than discomfort).
