Andrea: Where are the humans though, you know, people like Giovanni, Archer, and the Rocket grunts? I find it unusual for people who exploit Pokémon for the benefit of their organization to leave the facility in charge in said Pokémon. In fact, did you guys have trainers here; if so, who are they?
Andrea: "You don't believe the clones and hybrids here created themselves, now do you?"
"The Rocket Grunts don't live here like most of us do. They have their own bases of operation to stay at, especially since a lot of them are sent out to several regions across the sea. As for the big bosses like Giovanni? He mostly oversees everything we do. I've only seen him in person once in my life, so I don't know where he comes or goes but we're the ones who do most of his dirty work."
"Pokemon are simply beneficial for certain jobs, as well as communication, especially when it comes to important missions and the like. That's why some of us are put in charge of specific things like training rookies, and healing the wounded."
"Many Pokemon here do have trainers, while others don't. It all depends on how they ended up at Team Rocket to begin with. Plus the Grunts never leave without taking their own Pokemon with them."
"Cascade and Fievel weren't captured, they were created. Because of that, they don't have specific trainers that "own" them. But that doesn't mean they don't interact with humans. Obviously, the human scientists played the main role in creating them in the first place, so they closely monitor them to see if everything is still going well, as well as discussing whatever plans they have for them in the near and far future."
"As for me, I was captured in a Pokeball when I was young. So I suppose I do have a "trainer" of sorts. But seeing as I've been in charge of the rookie Pokemon here in my senior days, I haven't spent time around them in a very long time. Ultimately, the humans are also the ones who write out and assign missions to Pokemon who go out by themselves without the Grunts, my main contribution there is to simply hand those missions to them and report back successes and failures. Though, sometimes, I do get the chance of picking out the Pokemon I think are best suited for specific missions as I have the most personal experience with many of them. They trust me to make the best choice."
