Creator and Original Ownership
Was it ever confirmed that the Heat Gun was designed by Cisco? He always did only say the Cold Gun was his creation, and from his reaction in "Revenge of the Rogues", he seemed like he was only analyzing the weapon from what was described to him; it would be kind of weird if he truly built the gun, for he acted like not exactly knowing its function and still making discovery about it. Maybe that's just me? But that's how the ghostbuster talk sounded like to me. I know the gun along with the cold gun are currently in S.T.A.R. Labs' possession, but for this gun, I don't think it was made clear that it originated there. Did I miss something?
Does anyone ever notice or say that the Heat Gun looks like it has a fuel tank on it that enables it to shoot out its heat bursts?
