It's another daughter! She has black hair like his other daughter, but unlike Indigo, the baby has big black eyes and green skin. Shane names her Sage, after Wisteria's favorite herb, since she wants to be a chef, and Shane wants Wisteria to feel like Sage is her daughter, too, just as much as Indigo is. (Lucky for the baby that Wisteria's favorite herb wasn't Parsley!)
