A young man in his early 20s seems to pop up out of nowhere while Elsa did her run at the skate park.  He had dark hair and skin and a gold chain, not like a necklace chain but a chain chain, wrapped up one arm around his neck and then down the other arm under that he wore a leather jacket and tshirt and a pair of leather pants, he watches Elsa's routine, clapping as she finishes, "Nice run, I'm Seth, I have something for you," he hands her a folder (exactly like the one Jack got only with appropriate changes)
