I think if Quinn see Ray next time then there will fight between the two and since Ray is stronger then their is a high chance that the System will give a Quest to Defeat Ray like when it has given in Chapter 2096 and if Quinn is able to Defeat Ray then the Reward given will be equivalent to Ray's power making him almost overpowered. But i think it will be best if Quinn awakens his dragon bloodline since he is a descendant of Ray Talen who is a Red Dragon Sen, making him a Vampire-Dragon hybrid and it is also a best reward which is equivalent for defeating Ray.
