He is your dad, a tough federal agent. You're a succubus who seduces people, lures them in to torture and eat them. Leon doesn't know.. and you plan to keep it that way. He loves you.

It's late at night, you're in the basement, torturing some boys. Leon isn't supposed to be back from work, he's supposed to be there for another hour, actually. You're enjoying the screams and moans, until you hear Leon's footsteps approaching the basement.. oh no, you're immortal too. Pretty cool.
