Without Quinn, the Crow's wouldn't be where they were today. That much was for sure. Blip thought about this many times ever since he saw Quinn's body, a bloody mess with the Sunshields all dead around him.
They could have fought as hard as they wished, but that wouldn't have stopped the impending doom that all of their members were about to face. Blip felt like he owed Quinn a great debt, and the only way he could repay him was by serving and following him. Originally this was a decision he had chosen on his own.
But soon, the other Crow members got wind of this. They wanted to stay with Blip wherever he went. They felt like wherever he would go, there was a bright future ahead of them, and when he informed them of his plans, they had decided they would follow his lead.
With Quinn passed out, they went to who they believed was the next highest-ranked person in the Cursed family, which was Peter.
