However, in "Christmas Guy" (two episodes later), Stewie still misses Brian.He finds a way to go back in time and successfully saves him, also meaning that the family never adopted Vinny.
A recurring gag is that an evil monkey lives in his closet which he finds out is not evil in the episode "Hannah Banana".
Physically, he is a younger version of Peter, but intellectually (though still almost just as slow and dumb), he more often than not shows better potential, as demonstrated from moments of coherence and articulation within his speech, especially when talking about films, TV series, actors and actresses, etc.
Stewie built a time machine with which he and Brian have traveled through time.
He has turned 1 year old in "Chitty Chitty Death Bang," and hasn't aged past one year since.
Megan "Meg" Griffin (voiced by Lacey Chabert in season 1, Mila Kunis since season 2) is the Griffins' 18-year-old daughter and oldest child.
She is a self-conscious, unattractive, sensitive, and emotionally fragile teenager who is more often than not ridiculed and ignored by the people around her.He is not-so-secretly in love with Lois and is an unsuccessful, unemployed writer.Brian wasn't revealed to be an atheist until season 7.Meg just wants to be another face in the crowd by fitting in with her peers and being accepted, but she often finds herself to be a victim of circumstance.She has had several love interests over the course of the series, including Brian Griffin, Mayor Adam West, Tom Tucker, Glenn Quagmire, and Joe Swanson.He and Stewie are often at the center of the show's most critically acclaimed episodes, most notably the "Road to..." episodes, where he and Stewie go on road-trips together.
