Peter looked a bit amused. "I'm an empath. Niki has super strength. I won't deny that I might have the ability to 'rip you in half', but if I was one to do that, I don't know why you'd still be sitting there. Not dead yet, as you say. I don't know how to prove that you can trust me, but I am not going to let anything happen to that boy. He's safe here. Anyone who tries to harm him is going to find themselves in a world of hurt, likely before I even get a chance to throw in my two bits. He's with his cousin, Monica, who is also staying here."
Then he sighed, resting his elbows on the desk in front of him. "As for Niki and Jessica... I don't know how much I can help you. When I first met Niki, Jessica was gone. She told me about her, but she thought that part of herself died when Micah did. Now, Jessica's back. And so is Micah."
Then a gleam of anger crept into Peter's eyes, and his tone cooled, along with the temperature of the room. "And I'm not offering you a gun so that you can shoot a woman who has come to care for you and try to build back something of her life. I offered to give you a tranq gun so that, if Jessica emerges, you have some way to defend yourself against a woman who has no concern for consequences, and does have the strength as well as the anger to tear you in half with her bare hands."
