Chapter 64 - 64: Xander’s Confusion
There's no need to mention the usefulness of points; they are the common currency within Team Rocket, far more practical than the League's currency.
As for Pokémon, Skye, who is now Cain's administrator, holds his position today because he received a Koffing as a reward from Cain. They believe that if they had such an excellent Pokémon, they too could take Skye's place.
Items cover a broad range, from various berries and potions to rare moves and exotic treasures.
Regarding Cain's promises, since Skye received 1,000 points, no one doubted the truth of his words.
Thus, Cain has formed his own small faction on the Trial Island—or rather, a large faction among the participants.
This is a characteristic style of Team Rocket; under Giovanni, there are many factions, with smaller factions within the larger ones, competing and growing together.
Giovanni transformed Team Rocket from a third-rate gang into the colossus that can now rival the League, and the factional rivalries have been a major reason for that.
As long as the balance between factions is maintained, this vast power can be effectively managed.
Moreover, Giovanni is an extremely confident person with a charisma that makes his subordinates compete only with each other, without any hint of rebellion.
Of course, Giovanni's immense strength and the control of his powerful trump card, Mewtwo, are also key factors.
After teaching them a lesson and offering rewards and temptations, Cain had likewise ensured that this group would follow him without question. As long as his power was strong enough, all the small plots would be easily dealt with.
