So, this chapter has Chad begin to realise that he has Hollow powers, in the context that Hollows grow by absorbing spirit energy from their surroundings and their victims, which is why they go after humans with strong spirit power. So, what does this mean for Chad? Chad is going to end up once again realising that he isn't strong enough yet, because there's no way he's on the Espada level yet, even if he has another battle mode. But... with the knowledge that he has Hollow powers will come a solution. When this arc is over, I believe now that Chad is going to elect to stay in Hueco Mundo until the Winter War. By staying there he'll grow stronger as time passes, and by hunting Hollows he'll be able to absorb their spirit power, because he's not going to hunt down humans or Shinigami, but Hollows are fair play. It's the scenario in which he'll grow the fastest. Right now Chad's training consists of just fighting a lot, which is exactly what he'd be doing in Hueco Mundo, but on Earth his growth will naturally be slower.
