Julian Santiago is Zane's father in The Sims 3 Generations LP. He didn't appear in Season 2 despite being the grandfather of Kendra Santiago, Isaac Santiago, Lindy Santiago, Aiden Santiago and Tanner Santiago. He featured as the guardian of the second "New Kids on the Block".
He is described as "humble" by Lifesimmer as he raised Zane all alone in the absence of Zane's mother. It is possible that Julian was a Teen father because he was a Young Adult parent to Teenage Zane, which is rare in normal gameplay.
Julian was a prospective boyfriend of Luna Fenderson, but no relationship developed between them because Luna's sister Penelope married Zane, which would have made Luna her own sister's mother-in-law. It can be assumed that Julian left Lucky Palms after the events of Season 1.
If Julian were still a member of the series, he would be dead.
- In the Season 1 finale, when Justine was throwing a party, it is seen on party planner that Julian is still a Young Adult. This is odd because he should have became an Adult sometime between Parts 34 and 45; Zane and Julian are the same age.
- He is the only member of the Fenderson-Santiago family that didn't appear in the second season.
- Julian may have Spanish roots as the name "Santiago" originates in Spain.
