!SPOILERS! "Prove to me you're a girl by showing me your penis." This is the voice of the norm, insecure about gender (because gender is impossible to anchor, even to something as "objective" as sex); hence Lara poses a dire threat to their Symbolic. Lara's act of self-mutilation is also an act of self-determination: her agency is manifest in the negative, "I will be anything but a man." Astonishingly intimate.
