With ending of Big Mouth season 7 sees the Bridgeton Middle School kids move up to high school, but it’s currently unknown how old they’ll be when the show finishes or what time span the final season will cover.

Now that the Big Mouth cast return for its ending, but several plot details and character development still need wrapping up. With heavy themes of sexuality, identity, love triangles, and the monsters of puberty, plenty of Big Mouth stories are still deserving of a satisfying conclusion.

8 The Mystery Of The Masked Principal

The Head Of Bridegton Middle's Identity Is Still Unknown

The Masked Principal first appears in season 4 as a replacement for Principal Barron, who retires to Clearwater, Florida, to live with her sister. The gag parodying The Masked Singer keeps the Big Mouth characters guessing, but as of season 7, their identity has yet to be revealed. In the Big Mouth season 4 finale, "What Are You Gonna Do?" the Masked Principal breaks the fourth wall to tell audiences that they are director Roman Polanski, although it’s extremely unlikely to be true, considering Polanski’s past controversies.

Several other Masked Principal theories in Big Mouth still need confirmation, especially the ones formed by its characters. Matthew’s best guess is pop star Paula Abdul, whereas Samira suggests that the Masked Principal is Cathy Lee Gifford. Other possible candidates include Katherine Heigl, Suge Knight, and Richard Lewis. However, the mask is never removed from the Principal’s head, so their true identity is still a mystery. Even though the kids leave Bridgeton Middle, it's still important that Big Mouth resolves this storyline, especially one that is so prominent through the later seasons of the show.

7 Jessi Defining Her Sexuality (Or Explicitly Stating She Isn't)

Jessi's Attraction To Women Is Teased Throughout Big Mouth

Jessi’s sexuality is a conversation that crops up frequently throughout Big Mouth. At one point, she develops feelings for her best friend Ali, but her love bug always implies that it’s a platonic love more than anything else. However, in season 7, there are more hints of Jessi being anything other than straight. Jessi becomes overly fond of her stepmother, Caitlin, and Nick’s sister, Leah, which causes her some awkward moments. While the discussion of Jessi’s sexuality is repeatedly touched upon, it is never defined.

However, Jessi doesn’t necessarily require a label. There are a few characters who come out in Big Mouth, such as Matthew and Elijah, but Jessi doesn’t need to decide whether she is one thing or another. Many people in real life have a broad range of sexual partners without stating whether they have a specific identity, but if this is the case for Jessi, the show needs to acknowledge this. Jessi is still a brilliant and endearing character regardless, but the constant teases throughout Big Mouth deserve a payoff.

6 The Lola, Matthew, And Jay Love Triangle

Big Mouth's Biggest Romantic Conflict Needs A Conclusion

The love triangle between Lola, Jay, and Matthew in Big Mouth often seems to be over, only to crop up again and again. After Jay comes out as bisexual, he has relationships with both Lola and Jay. Both of Jay’s partners have their positives and negatives, and there isn’t one that overpowers the other in of who is better for him. By the end of season 7, Jay isn’t dating anyone, but some moments suggest he isn’t over either of them. For example, Jay and Lola’s relationship in Big Mouth seems to be over when she starts dating Kurt.

Jay does refer to Matthew as his “ex-husband”

Initially, it appears that Lola’s presence in his home frustrates Jay, but it’s clear that his ex in a relationship with his sibling is too difficult for him. In season 7, Jay and Matthew’s interactions are rather minimal, which is very suspicious, considering how deep their romance is before their break up. However, Jay does refer to Matthew as his “ex-husband” at one point, which implies that he isn’t content with their split. With Big Mouth ending, this love triangle is a storyline that deserves a good resolution, with Jay either choosing one or the other, or even being alone.

5 Montel's Decision To Be A Shame Wizard

Big Mouth Season 8 Will Also Wrap Up Storylines From Human Resources

In Big Mouth season 6, Connie and Maury’s child, Montel, is born. the canceled Big Mouth spinoff Human Resources, Montel decides they want to be a Shame Wizard rather than a Hormone Monster, which their parents eventually accept. However, Montel is completely absent from Big Mouth season 7, so there are still a lot of uncovered details that the show needs to address.

Montel’s decision to become a Shame Wizard is a groundbreaking moment in the Big Mouth universe. It shares parallels with other storylines that focus on transgender characters, like Natalie, for example. Although Connie and Maury are stunned by Montel’s announcement at first, they embrace their child’s wishes and let Montel be who they want to be, but Big Mouth hasn’t delved into their life as a Shame Wizard yet. Big Mouth season 8 will wrap up stories about its own characters and the monsters in Human Resources, and hopefully, Montel will be one of them.

4 The Fate Of Nick Starr

Nick Is Going Down A Path To Become His Future Alter-Ego

Depending on how much time Big Mouth season 8 covers, one storyline that is worth expanding and concluding is that of Nick’s famous alter-ego, Nick Starr. Nick Starr appears frequently in Big Mouth when Nick is anxious and starts dwelling on a possible future that is full of success but lacking in company and love. Big Mouth’s Nick Starr is the host of the fictional “Countdown To Money With Nick Starr,” a psychotic dystopian game show that awards its contestants with tokens to use the bathroom, but the success quickly goes to his head, and Starr becomes an egotistical nightmare.

Details of Starr alter throughout the show, primarily as they’re imaginary thoughts of Nick’s, but it seems pretty certain that his future is set in stone. If he does become Starr, Big Mouth season 8 needs to give the character serious development to further justify Nick’s change in personality. Regardless of whether Nick succumbs to his fate as the selfish TV show host or not, the final installment of the show must delve into his psyche and either push him in another direction or let him embrace his flaws and acknowledge he’s more than Nick Starr.

3 Coach Steve's Affair With Jay's Mom

Steve & Jenna Bilzerian's Relationship Has A Potential Future

In the season 2 episode “Steve the Virgin,” Coach Steve sparks up an affair with Jay’s Mom, Jenna, and loses his virginity to her. Although one of Big Mouth’s best relationships goes on brief hiatuses when Guy Bilzerian returns home, Steve and Jenna’s affair continues at points throughout the show. Steve loves being Jay’s “Gary,” a term he uses to refer to a secret stepfather, as well as having sex regularly. However, it’ll be interesting to see whether Steve and Jenna have any sort of future together.

Guy Bilzerian is a famous womanizer who cheats on his wife constantly, but that doesn’t mean he won’t be furious if he ever discovers her being unfaithful. Jenna briefly shows Jay a little black book that is full of information that can destroy Jay, so perhaps this will be useful in future episodes. She’s also generally unconscious in Big Mouth and only wakes up for short periods, but when Jenna’s with Steve, she is a lot more present and happy. While it’s unlikely that the two will end up together, if anyone deserves a happy ending, it’s Coach Steve.

2 Jay’s Mom’s Secret Daughter

Jay Always Hopes For A Sibling Who Will Love Him

Another unresolved storyline in Big Mouth that focuses on Jenna Bilzerian is her secret daughter. In the season 3 premiere episode, “Girls Are Angry Too,” Jenna mentions having a secret daughter during a meeting about Bridgeton Middle’s dress code. It’s unclear as to whether Jay and his mysterious sister share two biological parents or one or whether she is older or younger than him. Some Big Mouth season 8 theories suggest that Lola is a Bilzerian, which makes sense as Guy fathers many children, but as she’s only six months older than Jay, it seems unlikely.

There’s a chance that Jenna’s secret daughter may not be real at all

None of the Big Mouth characters mention being adopted, but someone new may arrive that ticks this box. There’s a chance that Jenna’s secret daughter may not be real at all. Jenna is permanently drunk and is often disconnected from reality, so perhaps this is all a delusion. While it’s unlikely, but not impossible, Jenna may become pregnant by Steve, so she gives the baby up without anyone noticing. The deep desire for a strong sibling bond is one of the saddest things about Jay in Big Mouth, so he deserves to know more about his unknown sister.

1 Devon's Absence

Big Mouth Voice Actor Jak Knight ed Away In 2022

Big Mouth’s Devon is a prominent character throughout the show, whose main storylines include his on-again-off-again relationship with Devin and his budding friendship with Missy. Devon is relatively absent in Big Mouth season 7, only appearing in the background for a couple of brief moments and never speaking. Behind the scenes, Devon’s absence is because of the death of his voice actor, Jak Knight, and the character is yet to be recast. It’s almost certain that Devon will not get a new voice, but that doesn’t mean that Big Mouth can’t give him a satisfying ending.

There is a running joke throughout Big Mouth that Devon is secretly an old man. He and other characters often reference this, and there are small details that feed into this narrative, such as the pharmacist telling Jessi about Devon’s medication in the season 2 episode “The Shame Wizard.” If there is any good way for Big Mouth to either kill Devon or give him a good conclusion, it makes sense for the show to lead with this recurring gag.
