Padjet was Ja-Kal's infant son 3500 years ago. The last time Ja-Kal saw Padjet and his mother, Tia, was when the prince was kidnapped by Scarab (assuming that's the whole story). Tia gave Ja-Kal an imprint of Padjet's hand. This hand-print is now a sad memory for Ja-Kal of the family he once had. Ja-kal doesn't known what became of is son and wife.
