Jinx Doesn't Have a Sister
Jinx doesn't have a sister, that's what makes her crazy. The fact that she thinks she has a sister when she doesn't only shows that she is crazy. She states, "You think I'm crazy? You should see my sister." Two assumptions one could make about this statement from a crazy person is that she either has a sister or she doesn't. If she does have a sister, Jinx would be implying that her sister is crazier than she is, but that's completely against what Jinx is about. Jinx's lore and audio only show how much of a maniac she is. If a sister that was crazier than her did exist, that would make Jinx seem less crazy and would make whatever she says seem more sane contradicting what she stands for (a crazy person). If she doesn't have a sister, she would be trying to prove that she is crazy by telling people she has a sister when she doesn't. Even if she wasn't trying to prove that she is crazy but at the same time not having a sister but saying that she does have one but really thinking that she has a sister when she doesn't only shows that she is crazy. Also, nothing in anyone's lore definitively shows that she has a sister.
