I'll tell you what, if someone manipulates you, then the reason is in you, and not in someone else.
If a person does not allow anyone to manipulate him, no one can do this.
And as for Tommy... Hurting him isn't really the worst thing to do.
And to be honest, yes, maybe Quinn is a bit of a cruel person.
She is one of those who gets her way by any means necessary.
Is this selfish? Yes, sure.
But it was precisely thanks to such selfish and cruel people that humanity managed to survive in competition with numerous and much stronger predators.
If our ancestors were such naive good-natured people as Jill, humanity would have died out long ago.
Quinn is a warrior.
She can hurt others, but she can also endure pain without complaining to anyone.
