Stewie Kills Lois and Lois Kills Stewie

"Stewie Kills Lois"

On Lois' birthday, Brian gives her a pair of cruise tickets with the intention of going with her. She invites Peter instead, disappointing Brian. Stewie is also upset at not being invited on the cruise, and he concocts a plan to embarrass Lois upon her return. Brian points out that Stewie has never followed through with any of his plans to hurt Lois. Stewie, disappointed in himself, resolves to prove Brian wrong. Meanwhile, on the cruise, Peter proves to be a frequent source of embarrassment for Lois, defecating on the poop deck and telling inappropriate stories at a dinner with ship's captain. Outraged, Lois walks onto the deck to be away from him, but is confronted by Stewie, who has traveled to the ship via speedboat. He shoots her repeatedly with a submachine gun, sending her overboard.

Six days later, Joe informs Peter that he has called off the search for Lois since he and his police squad cannot find her.

A year passes. Peter has begun dating again, some dates being a Stickman and Bonnie, but has talked Joe into posing as Lois from time to time so that her death doesn't emotionally scar Chris. Stewie indirectly reveals to Brian that he killed Lois. Disturbed and angered, Brian vows to bring him to justice. Stewie realizes that keeping the evidence of his crime as souvenirs is too risky; thus, he disposes of his gun and drawings depicting Lois being killed. After Peter nonchalantly reveals that Lois' life insurance policy, which was made on the cruise right after she and Peter had an argument stating they wanted to kill each other, has recently been cashed for a large amount of money, Joe, Quagmire, and Cleveland begin to suspect Peter as Lois' killer. They search the Griffins' trash and find Stewie's discarded gun and drawings. Joe becomes convinced that Peter was the one who killed Lois, given that Stewie and Peter have similar handwriting.

Peter goes on trial for Lois' murder. Carter falsely testifies against Peter, and Peter is close to receiving life in prison. However, Lois suddenly appears in the courtroom and reveals that Stewie, not Peter, tried to kill her.

"Lois Kills Stewie"

Following a brief recap by the Channel 5 News team, the episode picks up where "Stewie Kills Lois" ends.

Everyone is in disbelief that Stewie would try to murder Lois, but she insists that he is evil, and explains what happened. After falling overboard, she was rescued by a merman. Having developed retrograde amnesia, she starts working at a fat camp in North Carolina. While in a diner, she meets a new boyfriend, who turns out to be a white supremacist. While at a white supremacist rally, she takes a blow to the head and regains her memory, at which point she returns to Quahog.

As Lois explains her miraculous return, Stewie escapes. He ties up his family when they return home, and he kills Cleveland when he visits. He kidnaps Brian and forces him to drive him to the CIA, where he gains access to a supercomputer and takes control of the global power grid. The CIA submits to his demands, and Stewie becomes "President of the World".

Stewie, now a dictator, implements numerous cruel and unusual laws. Lois, unable to stand idly by as her son terrorizes the world, decides to assassinate him. After taking weapons from Stewie's own weapons vault, she engages him in a destructive battle in the Oval Office. Lois eventually gains the upper hand and prepares to kill Stewie, but cannot bring herself to murder her own child. Stewie takes the opportunity to disarm her, but, before he can kill Lois, he is shot and killed by Peter. They mourn over Stewie's corpse.

It is then revealed that what has happened was actually a computer simulation that Stewie created to see what would happen if he killed Lois. Brian wonders if a hypothetical external viewer of the simulation would feel cheated by what was ultimately a "dream sequence," but Stewie argues that a computer simulation is totally different. Stewie then claims that he is not yet ready to kill Lois or take over the world. Brian tells Stewie that hypothetical viewers would be angered by the simulation. Stewie counters by saying that at least the simulation didn't end like the final episode of The Sopranos, where it just cut to black mid-sentence. As Stewie is saying this, the scene cuts to black mid-sentence.

Production

"Stewie Kills Lois" and "Lois Kills Stewie" are the 102nd and 103rd episodes of Family Guy respectively. They are the fourth and fifth episodes of the sixth season of the show. "Stewie Kills Lois" was written by executive producer and former Futurama and South Park writer David A. Goodman. The episode was directed by John Holmquist. "Lois Kills Stewie" was written by recurring voice actor and future showrunner Steve Callaghan, and directed by Greg Colton. Colton and Callaghan previously worked on the season 5 episode "Whistle While Your Wife Works".

Before the airing of the episode, a 100th episode tribute special, hosted by MacFarlane, aired on Fox. The special showcases various clips of MacFarlane's favorite moments from the last 99 episodes of the show. It also included MacFarlane asking people questions related to Family Guy.

"Stewie Kills Lois" and "Lois Kills Stewie", along with the final five episodes of the fifth season and the first seven episodes of the sixth season, were also released on DVD under the title "Volume 6" by 20th Century Fox in the United States and Canada on October 21, 2008, five months after they had completed broadcast on television. The DVD release also features bonus material including deleted scenes, commentaries, and a 'making of' feature.

Both episodes aired before the 2007–2008 Writers Guild of America strike, and were the last episodes to air before it. In November 2007, Variety reported that MacFarlane had joined the strike and refused to complete more Family Guy episodes. A spokesperson for Fox said: "Our hope is that he returns to work and completes his non-writing obligations on those episodes". Fox aired two new episodes during November 2007. The following episode, "Padre de Familia", was the first of these two episodes to air. The strike ended on February 12, 2008 and the series resumed airing regularly.

In addition to the main cast, actors Patrick Stewart and Phil LaMarr, and American Idol judges Simon Cowell, Randy Jackson and Paula Abdul guest starred in the episode. The episode also featured the recurring voices of actress Jennifer Tilly and Patrick Warburton, and writers Danny Smith and John Viener in minor appearances. Future showrunner Mark Hentemann also made some appearances.

Reception

Ahsan Haque of IGN rated "Stewie Kills Lois" a 9/10, while rating "Lois Kills Stewie" a 9.4/10, saying "For the hundredth episode of Family Guy, Seth McFarlane and friends tackle the subject of one of Stewie Griffin's greatest ambitions — his not-so-secret desire to kill his mother. For the disturbed fans waiting for some form of a matricidal manifestation, you can feel comfort knowing, without spoiling too much, that the youngest Griffin absolutely means business and ensures that he doesn't fail this time around. [...] There are some tense courtroom moments, a birthday celebration with the gift of Lionel Richie, a cruise ship, machine guns, and the reappearance of the Kool Aid Man that help round out this carefully crafted and well-told cohesive storyline. With the amount of cheap manatee jokes kept to a reasonable level, this episode also manages to find an excellent balance between comedy and storytelling. It's a fantastic way to celebrate the Family Guy one-hundredth episode milestone. [...] With the writers' strike in full effect, it seems that this might be the last new episode of Family Guy we'll be seeing for a while. It's a bittersweet way to end the abruptly short season as the quality is reminiscent of the series' brilliance from the early years and it seems like the show was really starting to hit its stride for the season. Hopefully the series will be able to live up to the high bar set by this two-part classic upon its eventual return."

She did praise the cliffhanger, stating that she was intrigued about how the storyline would turn out. She also praised the storyline and liked how it was able to create drama. In her review of "Lois Kills Stewie", Koski rated the episode a B, calling the end of the story a bit predictable as she thought that the deaths of Lois, Cleveland and Stewie were a one time joke.
