When seeing a nest crystal in person, there was the opportunity for Quinn to use it to upgrade his system. There were two in total, and Quinn had decided to use one for Vincent's body, and not for a single moment did he regret that decision.
Although he never intended it to work out like this, it was a good thing that he could have a clone of himself, and it had come in handy during the Pure situation. On top of that, every time he saw Vincent, a warm feeling would overcome him. It was one of the decisions he was happy about.
The other nest crystal was used to continue creating the human clones to feed their blood to the vampires. Still, he hadn't given up on finding a nest crystal and had decided to ask for one of the vampire families to search for it.
Before Quinn went off to meet Sam and the others, Jin, the fourth family leader and the one in charge of the expedition, came forward to talk about something. The two of them walked slowly into the stadium to speak their mind.
