I'm no expert on Red's character, but his daughter Scarlet (get it? heh) was a spontaneous creation of us comment RPing one day. She's one of Red's kids from his wild days of sleeping around with tons of hot chicks. How I understand it, Scarlet's mother was one of Red's longer lasting relationships not sure if they ever got married though. Since their break-up or maybe even during their relationship Red was into some sketchy criminal activity and got locked up. Since getting out Scarlet now a teenager during our inital RP wants to reconnect with him, which he's reluctant to do at first feeling he's a bad influence. Scarlet fricken adores him regardless of his past though.
I assume this must be from before his incarceration, but a thug like Red can't help but rub off on his little girl. Here we see a sweet scene where Red and little Scarlet are enjoying a little visit to the park. Red offers to help teach Scarlet to aim and shoot a gun (a squirt gun in this case). Not sure if it was his idea or maybe she's caught a glimpse of daddy 'working' and wants to be like him. <3
