A dog is implied to be killed violently, though the dog is not seen (obscured by grass). The killer behaves very violently and is covered in blood afterwards.
In the first scene a trans woman is accidentally misgendered by a friend. He corrects himself quickly and moves on. To me it implied a recent transition. Throughout the rest of the film, the trans woman character is portrayed as competent, confident and respected by her peers. Her transness is treated matter-of-factly and doesn't ever come up again. The actress was also the producer of the film.
