Z has Hemophobia (Fear of blood) so that’s why she kills quickly and makes the kill clean as possible, or she uses a bow and arrow to shot from far distance so she doesn’t see the blood. So when she got cut by Project’s knife she had to see her blood as she was holding her eye and freaked out and panicked so badly that she blacked out.

Z and Lyssa never got any attention so when Z got in the murderlies she would make peoples day when their sad or she just wants people to have something she didn’t have.

She met Zmokey when she was patrolling the area in the woods around the murderlies territory and fought but they ended up stopping and realized they had same problems and became friends.

Her white streak in her hair glows in the dark so that’s how zmokey spotted her in the dark woods, and the necklace she wears is the last piece of Lyssa that she has left of her before Lyssa “moved”
