So what combinations of Greek and Egyptian mythology do you think the third crossover is going to give us?

Son of Sobek had Carter and Percy fight a greco-egyptian monster, Staff of Serapis had Annabeth and Sadie fight a greco-egyptian deity. What's gonna happen here? I don't think Setne is going to fight all four heroes alone, I just don't know who or what he's going to call on to help him.
