S5E22 Better Luck Next Time

Inside a warehouse, two men grapple for control of a firearm, their fight echoing past conflicts between them. After a fierce struggle, one man manages to seize the gun, triumphantly proclaiming himself the victor. However, he accidentally shoots himself in the process. As he lies dying, a blue energy entity emerges from his chest. Just as the other man prepares to make his escape, the police arrive on the scene and take him into custody.
