I would not speak of redemption, because that presupposes repentance, which Quinn is not said to ever have; it all depends on her motivations. Quinn could apologize for going behind Sage's back without being repentant for what she did, remaining true to herself.
Redemption? Repentance? Are you serious?
Did she kill someone?
What should she repent of ? And to whom? Maybe Sage?
Well of course...
But first, let Sage bring charges against her "daddy."
The one who provided her with a comfortable existence.
For some reason, it seems to me that she won't be too strict with him.
This world is imperfect. Everyone has their sins.
Fuck repentance. Only sick psychos repent, or those who have been cornered, and they have no other choice.
But yes, Quinn needs to figure out how to trick all these "decent" jerks.
