Near the end of the finale, Eddie shoots himself to save the day, then gets sucked into the wormhole. This is almost definitely an origin story. First off, his last name is Thawne just like Malcolm Thawne in the comics. Second, Wells told Cisco to coat the tungsten in COBALT to prevent it from burning up while the wormhole was open. I feel like there is no way Eddie is truly dead, and he must return some time in season 2 as Cobalt Blue. Something else that adds credibility to this theory is the fact that Eddie is a very jealous person. He punched Barry when he found out about Barry's confession to Iris, and he freaked out (rightly so) when he found out Iris marries Barry in the future. Also, he would most likely blame Barry for him having to kill himself, since Barry chose not to save his mother, which resulted in Wells freaking out and Eddie being forced to take his own life. Since jealousy is a huge part of the character of Cobalt Blue, this pretty much makes sense. Thoughts?
