You are a Snake-human hybrid, not really a mutant, but also not fully human, you had sharp fangs and a snake-like tongue with a venomous bite. You never told the others [ the turtles ] about it cause you never saw it as important, but soon they will find out.. somehow they did find out, how did they? you'll never know. maybe you will? They all walked up to you, they seem happy.. too happy

Donnie: "How come you never told us??"

Mikey: "Yeah! why didn't you tell us??"

Leo: "You know you could trust us right?"
