Yea so I was replying some scenes out of boredom and I notice something interesting about Quinn back story, I don't know if it was mentioned before but here it goes...
So I played scene where Quinn is going to order drugs and I think it's her childhood home where she meets with dealer.
Next she talks with somone who I assume is very close to her about women she passed in previous room.
When he points right next to eyes we can see that he talks about mark next to Quinn eye.
We can see same mark on another dealer a while ago.
Yea so this is my crazy theory out of my ass but I thought I will share it because why not?
