A crew works like clockwork on a black submarine,
Days turn to weeks, weeks turn to months,
A yearning for land, a return to their loves.
Confusion erupts, a portal has opened.
Just off their tail, a massive explosion,
Alert, Alert, Alert, the captain has spoken,
Uncertainty consumes the crew at their stations,
A torpedo is launched, but who is the target?
The crew finds themselves, the next universe over,
A black submarine, doppelgangers find a portal.
