Now I'm wondering how much of Jace's obsession with the armed forces (especially the Marines) comes from that movie.Maybe he sees and idol in Cena after watching The Marine but there's no way he became a fan of Cena from wrestling.
We don't know of any relative of his in the armed services, so we're left to believe that his obsession probably began with some pop culture portrayal of the Marines. I'm thinking that movie was the starting point for a lot of obsessions for Jace. He can barely mention the Marines without mentioning Cena. I think The Marine might be Jace's Sonic the Hedgehog.
