Hunt the Gold
It was revealed that instead of gold, the chest that Captain Cold and Heat Wave were after, was of Brotone. When they found this out, a fight breaks out between Cold and Mari McCabe and Diabullet. When Firestorm intervened, Cold fired an ice beam at him, making him crash into the chest and exploding in the process.
