Quinn and her father both think they are masterminds just because they know how a chess board looks likeQuinn is not so threatening, she thinks she is like her father but in reality she doesn't know how to deal with the consequence of her actions.
Rex being dead showcases how his big plans played out and quinn is a good daddys girl and following his footsteps and is being played by everyone while they arent even really trying.
Lily looks like two seconds at quinn and has her completly figured out and disarmed, Quinn is all show and her only solutions are throwing her friends in front the bus.
She would make an amazing couple with Nika from SG, two wannabe masterminds fucking up at every step, overestimating themselves and their capabilities right into the grave.
Shes still a fun girl tho
