I genuinely love Mar's moments of insanity, if only for the way it injects chaos into Hanna's life, and forces her to commit to the friendship. Mar and Hanna both seem to possess a death drive, an anger turned inward that manifests in self-destructive acts. Hanna is maybe a bit more aware of this (we'll see in a couple more pages), but she can't seem to stop it. The closest she can get is keeping Mar out of trouble, a kindness of which Jacques has assured her she's not capable.
