A desperate Banana Joe seeks the help of Gumball and Darwin in order to find his missing mother.
- Accidental Misnaming: Gumball can't get the hang of pronouncing Banana Barbara's name properly. He only gets it right after Banana Joe spells it out... badly.
- Ambiguous Syntax: Banana Barbara "played a chicken" in a stage show—as an instrument.
- Alas, Poor Villain: Gumball and Darwin feels bad about Rob being erased out of existence so they got Banana Barbara to repaint him back.
- Cassandra Truth: Whenever Barbara's future painting show static, Rob assumes it isn't working. He never considers that the static is the future.
- Cessation of Existence: Rob is erased from existence by Barbaras painting. Thankfully he is painted back... but seems to either have been put back in the Void, or returning only for The End of the World as We Know It.
- A Day in the Limelight: For Banana Joe and Banana Barbara. Barbara in particular, as the nature behind her paintings is elaborated.
- End-of-Series Awareness: Barbara's line "There is no future" really leans on the fourth wall with regards to this being the show's final season.
- Exact Words: Banana Joe doesn't think his mother suffers from mental problems—she enjoys them.
- Not Quite Back to Normal: After asking for Rob to be restored after erasure, Gumball suggests punishing him by adding something embarrassing "like a goatee or a third nostril". Barbara gives him a pig's tail.
- Poor Communication Kills: If Rob just told the trio what was going on rather then kidnapping Barbara and trying to kill the trio during the rescue attempt, they might have listened to him instead of erasing him.
- Rewriting Reality: Barbara can actually alter reality with her paintings (and may have been causing the future rather than predicting it). At first she uses it to alert Banana Joe, Gumball and Darwin where she is, but when that fails she simply paints a portal for them to stumble into. Rob then uses this power to attack them; for example, by drawing a crack in front of them, or changing the floor into water. Eventually, they turn the tables on Rob and erase him out of the painting, and out of existence.
- Save the Villain: After erasing Rob from existence, Gumball and Darwin ask Banana Barbara to use her painting to restore him.
- Sequel Episode: Returns to the topic of Banana Barbara's prophetic painting shown in "The Oracle".
- Sequel Hook: Every time Banana Barbara tries to paint the future, it's nothing but a static pattern, and she even says there is no future. The painting that has the Wattersons inside the void has yet to transpire.
- The Un-Reveal: The reason why Rob kidnapped Banana Barbara and what he considered bigger than Gumball himself was never revealed because he was erased and repainted back into The Void. The closest indication is that he wanted to know what the future held, as every time Barbara painted static, he told her he wanted to know the future and to do it again.
- Vagueness Is Coming: Its not revealed why Rob wanted to know the future, and Barbara's claim there is no future is shortly after followed by the screen turning to static, a silhouette visible within it. In hindsight, this vague figure is revealed to be Superintendent Evil from "The Inquisition".
- Villainous Breakdown: Rob loses it when he's about to be erased.
- Well-Intentioned Extremist: Whatever Rob was planning, it had nothing to do with Gumball, and just as Gumball is about to erase him, he cries out they have no idea whats going on, nor what he's trying to stop.
- Wham Episode: Thanks to Gumball, Darwin, and Banana Joe, Rob is back in the Void. The future paintings keep depicting ominous static patterns, meaning that something (likely bad) is going to happen in the near future.
- Wham Line: At the very end of the episode, after Gumball says he'll see Rob in the future.Banana Barbara: But there is no future.
