In yet another "Road to..." episode, Brian and Stewie head off to Vegas, but they use the teleporting machine, which malfunctions and creates two clones of themselves, who each have their own Vegas experience.
Tropes:
- Ambiguous Clone Ending: It's never revealed which pair are the clones, but given that one Stewie and Brian from each set died, one of them is definitely a clone from that point onward. Not that this matters or is even mentioned again.
- Better to Die than Be Killed: Stewie uses this to convince Brian that they should kill themselves instead of letting the loan shark's goons get them. Stewie ends up backing out at the last second, however.
- Blatant Lies: Both the lucky Brian and unlucky Stewie realize that something happened to their respective counterparts, but neither is exactly forthcoming about the details.
- Dirty Coward: This is how the lucky Brian and unlucky Stewie get their respective companions killed, because they were too lily-livered to face adversity.
- Cornered by a hitman demanding money, Lucky Brian tells him to shoot Stewie because he's a baby and "won't even remember being alive."
- Unlucky Stewie convinces Brian that they should kill themselves in order to spare the rest of the family from being targeted by the hitman, but ends up clinging to the railing at the last possible second.
- Driven to Suicide: With no money and faced with a loan shark sending a hitman after them, the unlucky Brian and Stewie decide to jump off the balcony of their hotel. Stewie chickens out at the last second.
- Even Evil Has Standards: Granted, Stewie isn't exactly evil here, nor is he actually fond of his mother Lois, but the unlucky Stewie is horrified to hear that the unlucky Brian secretly borrowed money from Lois for the trip. After finding the lucky pair's money and encountering the lucky Brian, this Stewie remembers the unlucky Brian's admission and hides most of the money to allow himself the opportunity to return Lois's money as soon as they get home.
- Gallows Humor: The unlucky Stewie suggests he and Brian kill themselves because they're dead no matter what and this way it will be "quick and clean." Not for the hotel staff, but that won't be the pair's problem.
- Kick the Dog: Kill The Cat to be more specific. Lucky Brian hires a sniper to kill Quagmire's pet cat Principessa.
- Loan Shark: After losing all their money gambling, the unlucky Brian and Stewie get money from a loan shark to bet on a basketball game that they're told is fixed.
- Manchild: Brian has to confiscate a pair of scissors from Peter, who wanted to make an owl mask.Brian: Peter, use your scissors.Peter: But they're not sharp! (throws a hissy fit)
- Missed Him by That Much: The lucky and unlucky pairs come within close proximity a few times, but don't realize what's happened until the end. The closest they come to interacting is when the Stewie clones take each other's backpack.
- Twinmaker: Stewie's teleporter creates a duplicate pair of them, who end up having a very lucky time in Vegas.
- What Happened to the Mouse?: The unlucky Stewie finds the lucky pair's fortune. While he presumably repaid the loan shark, we don't actually see it as it cuts to him buying a bus ticket back to Rhode Island. But he does keep a huge chunk of it, part of which he intends to repay Lois on Brian's behalf.
