Jenny Schecter, played by Mia Kirshner, was one of the main characters on The L Word. She is the character that fans love to hate.
In many ways, she is the epitome of the problematic bi. She is narcissistic, unfaithful, and indecisive. She begins the show in a relationship with a man and then proceeds to cheat on him. Throughout the show, she has a series of romantic relationships, but is generally portrayed as being damaged.
In season three, she becomes involved in an incredibly involved revenge scheme in which she once again uses her sexuality and sex appeal to manipulate and hurt those around her.
In season six, it is revealed that Jenny was murdered, but we never find out who killed Jenny Schecter.
