The fact that his current scamming involves stealing people's identities leaves the door pretty open for him to take on yet another alias if things go sideways. The expectation, with the way the show has been structured using Gene as the "end all, be all", is that Gene either gets caught or gets away with it for good by the end.

But what if he once again takes on a new identity and is fated to live his life forever without anchors in a game of cat and mouse against the law, and himself? No evolution, just devolution. No reunion or return to a better place, just perpetual angst and self destruction doomed to repeat itself. The curse of la cucaracha -- you'll never stomp him out, but does that really make him a winner when its all said and done?
