Season Four ends with several cliffhangers[]
- What happened to Lucille 2? — Buster is arrested for Lucille Austero's murder although every Bluth has motive for her disappearance. Furthermore, no evidence has been shown she is actually dead.
- Who played Thing in Fantastic 4: An Action Musical? — Tobias gives the Thing costume to Buster, who leaves it by the Chicken Dan's tent before punching Herbert Love and fleeing. Yet Thing is seen (poorly) dancing in the floating train wreck of a musical.
- What is Michael ashamed of? — Michael returns to the model home late the night of Cinco wearing a banana stand yellow shirt, and is extremely ashamed of something he did. Is it connected to Lucille 2's disappearance?
- What happens to the US/Mexico wall that George and Lindsay want to build? — Lindsay was (accidentally) hosting a successful rally to build the US/Mexico wall. Will it get built?
- "*What happens to Fakeblock? — George Michael's fake company Fakeblock is based on a software that doesn't exist. At the end of the season George Michael is being sued by P-Hound for the ownership of Fakeblock and is, unbeknownst to himself, also being threatened by the hacktivist group Anonymous (who leave him the misinterpreted note "you are about to get screwed like you've never been screwed before") because of Fakeblock's alleged anti-piracy abilities. On top of it all, he is also committing fraud, as Fakeblock doesn't actually have any of its (vaguely) advertised capabilities.
==A handful of smaller stories that could be explored further==
- What happens to George Michael's relationship with his father Michael, and their lover's triangle with Rebel Alley?— George Michael and Michael's tug-of-war over Rebel comes to a head when George Michael steps up to his father and punches him.
- What happens to the US/Mexico wall that George and Lindsay want to build? — Lindsay was (accidentally) hosting a successful rally to build the US/Mexico wall. Will it get built?
- Maeby's life as a sex offender
- Lindsay's congressional run
- G.O.B. in a post-Tony Wonder world
- George Sr.'s loss of testosterone
- A newly forgiving and loving Lucille
- A post-explosion Tobias
Who played Thing in Fantastic 4: An Action Musical?[]
Tobias gives the Thing costume to Buster, who leaves it by the Chicken Dan's tent before punching Herbert Love and fleeing. Yet Thing is seen (poorly) dancing in the floating train wreck of a musical.
This was the first season four cliffhangers to be resolved. In "Family Leave", when Lindsay moves away from Herbert Love's body we can see Gene Parmesan walking in while holding the Thing costume in his hands.
George Sr.'s loss of testosterone[]
In "Rom-Traum" in Mexico Tobias gives George a package which has estrogen pills inside. Michael realizes that for the past two years his Mom has been giving his Dad estrogen pills which is why he is the way he is.
