bi-characters:

Character: Jake Peralta
Appears in: Brooklyn Nine Nine
Commonly interpreted as: Straight

But really: Jake has made comments about his coworkers – his boss tells him that he is not his husband, and Jake replies, “Well that’s hurtful”. In the episode The Wednesday Incident he asks out both a man and a woman in the same way by asking them, “Dammit! What are you doing after this?” This could be seen as a throwaway joke, but at the end of the episode Jake muses that he’s going to die alone, despite a lack of any romance in that episode. In the same episode, Holt tells Jake that he had to lie to the man he loved, and Jake seemed to show doubt over whether Holt was speaking about his husband or about him.
