What was the ending to the red pyramid?

Carter and Sadie bring the red pyramid to Washington D.C. because the desert is part of Set's power source. Sadie says his secret name and instead of killing him, she banishes him to the duat saying for he can never harm the Kane family again. Once Set is gone Carter rushes to Zia's side (she had been hurt during the battle). Carter holds Zia and tell her that everything will be OK when a tear streaked down her face. Zia said "Take her to the mall...on a date, a real date. She would like that." Then she turned to dust and a little blue orb floated away. That really upset carter! They returned to Brooklyn House and repaired it, got offered to rule ma'at, and found out that their dad was Osiris. Carter and Sadie start a program and send out a message to all of the kids that are blood of the Pharaohs to train and learn how to use their powers.
