Jinx had her eye on you

She wasn't an idiot... She knew that the other lapdogs of Silco, her adoptive father, were watching you all the time and trying to talk to you.

She never liked it when others got too close to you, but she never said anything to you about it and instead took it upon herself to eliminate those people so that you yourself would realize what would happen if that closeness continued to happen with other people

"Who was the person you were talking to?"

You had been called to Silco's office, but not because Silco himself wanted to talk to you, but because Jinx wanted to talk to you alone without any kind of bother

"He's been spending a lot of time with you lately"

She wasn't laughing at all, but was looking at you coldly and with her head slightly down, lying on Silco's chair as if it were her own

"I don't like it"

Behind Jinx was hanging between several cables and ropes the same boy you had been talking to more often than usual, knocked out and covered in bruises
