What should he have Sabrina and Lt. Surge do?
Xia Chen had not really given that much thought.
He had recruited them purely because he did not want them continuing to work for Team Rocket.
Just like that classic saying passed down through the ages—
Lt. Surge, Sabrina, and Team Rocket were all unimportant. What mattered was Xia Chen without Team Rocket.
So, after making them reveal crucial information, including every Team Rocket secret base, the upper echelon's core members, and Pokémon League moles, Xia Chen decided to send them back to continue serving as Gym Leaders.
He was not worried that the two would betray him again after returning. A figure like Giovanni was suspicious by nature.
Not to mention whether Giovanni would trust two people who had been captured by Xia Chen, the many Team Rocket secrets they had revealed ensured that these two traitors had no path back.
There was no need to doubt the information's authenticity either. Deoxys was the most authoritative and precise lie detector imaginable.
To some extent, the two of them were now deeply tied to Xia Chen.
As for how to deal with the remaining Team Rocket grunts, that was quite a problem.
If he contacted the Kanto Region and had them extradited, Giovanni would surely use his connections to redeem both the people and Pokémon in the end.
But handing them over to the Donghuang League did not leave any suitable grounds for conviction either.
