Corrected entry: Bonnie had Susie in season 7. In this episode they go back in time before Susie was born, Stewie is a year older than Susie so it makes no sense why he would be re born again. He's always a year old throughout the entire series.
Correction:They didn't go back in time. When the time machine broke, time started moving backwards. When Stewie saw Bonnie was pregnant, he realised events were being undone, which means he would soon be unborn. Time kept moving backwards until Stewie was unborn. When Brian fixed the machine, time went forward and Stewie was born (which would be a year before Susie was born).
Plot hole: They're in the Clam complaining that they can't drink when they make the revelation that Brian can because he's technically 56. But Quagmire should be able to drink, as in a much earlier episode, he's revealed to be over 60.
Suggested correction:Quagmire considers the rest of them to be his best friends. He isn't drinking because they can't drink. He is complaining because since his friends can't drink - he won't drink, so he is still pissed.
It's still a plot hole considering Quagmire's age. I think the writers messed up big time.
You make a good point, but it's awkward to be that one person who is drinking while surrounded by people who can't. So, I understand the correction that was submitted above. Because his friends are not drinking, he now feels that he can't.
It's 100% a mistake. Quagmire simply would buy them alcohol the same way Brian did when they realized he could.
Connie: You know, Meg, there's no dogs allowed. So, you're going to have to leave. But Brian can stay. Brian Griffin: You know, Connie, I think I have this theory about why you're such a bitch. Connie: Excuse me? Meg Griffin: Brian, let's just go. Brian Griffin: No, no, no, no, no, no. Hang on a minute, Meg, hang on. You see, Connie, you're popular because you developed early and started giving handjobs when you were twelve. But now you can't stand to look in the mirror because all you see is a whore. So you pick on Meg to avoid the inevitable realization that once your body's used up by age nineteen, you're gonna be a worn out chalky skinned burlap sack that even your own stepdad won't want. How is that? Am I in the ballpark? [Connie runs off crying].
