The condition that the Ouroboros Queen wanted Emery to do, in order for him to pay back her protection and the resources he had received from the Ouroboros, was to return to the facility once a week where he would go through intensive tests on his bloodline.
Even though he was reluctant at the idea, the queen assured him that she would not do anything that would endanger him. She told him that through continued research and testing, they would hopefully be able to create an improved version of the Fey Serum – one that could further enhance his bloodline gene.
On top of that, she even offered him another set of clone frames to be made for him as a reward. After considering the offer, Emery eventually agreed to cooperate, thinking that he might need another clone body in the future.
With that, the deal was made.
