The early seasons have a lot of underlying transphobia.
Season 1, episode 21 I think has a trans woman character who is repeatedly misgendered after it is revealed, and transphobic jokes & comments are made about her.
Season 1 episode 17 has a passing mention of a man carrying out a revenge prank on a friend for setting him up on a date with a “transvestite” as a joke.
Season 1, episode 21, one of the agents refers to a trans woman by a slur at the very end of the episode in a conversation with another agent. It has no relevance to episode and can be avoided by skipping the scene after the agents return to headquarters.
Season 1, episode 20: the plot relies heavily on the murderous transwoman trope. Includes misgendering, mocking, exaggerated disgust response, and the execution of a trans character, among other things.
There is a scene where someone has their throat slit and their eyes gouged out, leaving empty sockets. You don't see the act, but you do see the body and the aftermath, as well as the aforementioned eyes on a kitchen counter later in the show.
