The Technician was sure that there was much more to Star Energy, but he also knew that Nick was essentially the leader of humanity's true resistance.
He was the one who controlled the secret research camp, and he was also directly working with the Sun.
The Technician knew that Nick knew more about the true state of the world than anyone else.
Sure, the old Champion of Light once used his ability to create an isolated space in which he could tell them everything he knew, but that had been a one-time thing, and it had angered the true enemy tremendously.
They didn't know what he had told the Shields, but they knew that he had gone behind their backs.
Because of that, they had weakened him tremendously until it was time to create a new Champion.
Naturally, the aliens had also considered killing all the Shields, but that would be wasting a gigantic chunk of time and progress.
