Answer

While it might seem a great thing, the reveal had Emery on edge. After all, it basically told him his body had been tempered without his knowledge or consent. Who knew what they put in him while he was unconscious. 

The last thing he needed was for another Lucius situation to repeat itself.

Therefore when they told him to take some time to consider the matter. That in the meantime they would have some tests carried out on his body, he gladly accepted. It hadn't been long since Emery had awakened and he really needed some time to process everything he had just learned.

Headed by Grand Master Reikun, along with several Apex experts he had seen before, Emery underwent several tests to find out more about his condition in a closed facility within the Silvermane Palace.
