- Made a Slave: She committed a serious crime (although it is not said what the crime was) and serving Charlie is her punishment. The series zigzags how justified this is. As Tanya points out, slavery is morally wrong and the legal system punishing Quill is defunct. On the other hand, Quill was a terrorist and war criminal, and the viewer has little information as to the gravity of what she did, though Charlie's insistence that they were terrorist acts partnered with Quill's temperament lends to the impression they were fairly heinous.
