Jupiter, Guyot was never a partner with the three rebels. Luggnagg and Jabir are just using Guyot to get what they want, just as Guyot is using them to get what he wants.
Guyot was also told that he had be given a dummy crystal from the start.
Luggnagg, Jabir, and Khan only rebelled to understand the Guyver and its secrets. They were curious as to why Guyot would rebel, and questioned Archanfel's method of using only Murakami to capture the Guyvers.
Luggnagg and Jabir still don't know why the Creators left, and the power a zoalord guyver could wield.
Guyot still has the upper hand in this sense. Plus, there maybe the possibility of Guyot still having the Remover.
