In a captivating twist, Sheldon Cooper from The Big Bang Theory created speculation among fans when he declared that he has exactly nine friends. With the advent of the upcoming spinoff centered around Stuart, the question arises: how many of these friends might appear in the new series? Among the four confirmed characters for this spinoff, it seems that not many would meet Sheldon’s criteria for friendship. Notably, while his character evolved significantly throughout the series, the query regarding his nine friends traces back to earlier seasons, reflecting a different stage in his emotional journey.
The specific moment occurs in season 7, during the episode titled “The Discovery Dissipation,” where Sheldon determines his friend count to be nine. This figure fluctuates later on, especially after Leonard challenges Sheldon’s claimed breakthrough on a new element. This brings to light a long-standing mystery among fans: who were the original nine friends? Although Sheldon’s appearance in the spinoff, titled Stuart Fails to Save the Universe, seems unlikely given Jim Parsons’ retreat from the spotlight, the spinoff could still connect to him through familiar faces from his circle.

The Main Big Bang Theory Cast (Excluding Amy)
He Names A Few of Them Specifically




As for Leonard, David Galecki’s decision to focus on life in Nashville rather than return for the final season of The Conners implies that he’s unlikely to reprieve his role in the spinoff. However, other characters from the original series may be available for guest appearances. Sheldon acknowledges Howard and Penny as friends in season 7, and considering his closer rapport with Raj and his willingness to confront his mysophobia to sing to Bernadette, it’s reasonable to assume they might also be included in his friend circle.
Amy also remains a possibility for a reunion, evidenced by Mayim Bialik’s recent role in Night Court. However, whether Sheldon truly regards her as a friend becomes debatable. Although he initially labeled her as such, Sheldon’s rigid worldview suggests he distinguishes between “friend” and “girlfriend,” which complicates their relationship. This unique perspective leads to a friend tally that currently stands at five.

Stuart Bloom
His Friend Status Is Up for Debate





Among the confirmed cast for the spinoff, Stuart is arguably Sheldon’s closest connection to friendship. It’s worth noting that Sheldon holds little respect for Kripke, even less for Bert, and barely knows Denise. While Stuart stepped into Howard’s role during Howard’s space excursion, it’s crucial to recognize that Sheldon’s gratitude for Stuart was fleeting. He readily replaced Stuart when Howard returned, only changing his stance after Stuart offered a discount on comic books.
Even if Sheldon’s total friend count rests at five, Stuart remains significant, as he could pave the way for the inclusion of many of Sheldon’s genuine friends in Stuart Fails to Save the Universe. The presence of characters like Bert and Kripke might allow for guest appearances by Howard or Raj at Caltech. Moreover, Stuart’s comic book shop stands as a potential crossover point that invites numerous characters from Sheldon’s past.

Wil Wheaton
They’ve Come a Long Way Since Their Feud





While many fans might speculate about Sheldon’s potential ninth friend, it’s likely that James Earl Jones doesn’t qualify since he and Sheldon met after the nine were identified. However, Wil Wheaton had been a key part of Sheldon’s circle since season 2, making it understandable why Sheldon professed Wheaton as one of his friends. Not only did Wheaton help Sheldon emerge from personal doubt, his connection opens the door for potential appearances in the new spinoff.
Wheaton’s ties to Star Trek and previous guest roles make him a prime candidate for a return, especially during any events linked to Stuart’s comic book shop. His popularity as a guest star on The Big Bang Theory emphasizes that his involvement would be well-received should the spinoff engage him for a couple of episodes.

Professor Proton
He Was Way More Forgiving Than Bill Nye





Sadly, the passing of Bob Newhart has eliminated the possibility of any future appearances as Professor Proton in the franchise. Even in the case that he were still alive, the fate of his character on The Big Bang Theory complicates any chance for a comeback. With Newhart’s appearances after Professor Proton’s death being confined to Sheldon’s dreams, the character’s return in a physical form remains unlikely.
Nevertheless, Sheldon appears to have regarded beloved TV scientist Arthur Jeffries as part of his circle of friends. Unlike Bill Nye, who distanced himself from Sheldon’s antics, Jeffries was more tolerable of Sheldon’s quirks. Given that Professor Proton did not pass away until half a season after Sheldon makes the nine claims, it’s reasonable to believe he would have ranked among Sheldon’s acknowledged friends. As evidenced by Sheldon’s reverence for Proton as a guiding figure, this friendship held considerable significance.

Beverly Hofstadter
They Nearly Became More Than Friends





Leonard Hofstadter’s mother, Beverly, is portrayed as an exceptionally neglectful figure, yet she shows appreciation for Sheldon, treating him in a manner reminiscent of a desired son. As an esteemed psychologist and author, she’s known for her insightful commentary, which makes it even more eyebrow-raising when she drunkenly kisses Sheldon in his living room. While Sheldon might not have grasped the implications of such an encounter at the time, he still respected her as an intellectual equal.
It’s important to note that Sheldon respects many individuals without necessarily labeling them as friends. However, his excitement upon Beverly’s arrivals stands out, indicating a deeper connection. As she is unlikely to appear in the spinoff without reference to either Sheldon or Leonard, her chances of resurfacing in future storylines appear slim.
2
Stephen Hawking
The Game Is Literally Called “Words with Friends”





In season 5, Stephen Hawking’s first appearance marked the beginning of a loose professional friendship with Sheldon. Their relationship evolved in season 6 when they engaged in playful competition through the game Words with Friends. Sheldon explicitly labeled them as friends, a claim bolstered by their subsequent interactions. Although Hawking’s real-life passing halts his possible return in Stuart Fails to Save the Universe, references to him may still appear in various forms.
Episodes featuring Hawking have demonstrated that he can still be acknowledged in spirit; Howard’s toy created in honor of the renowned physicist serves as a potential narrative device. The spinoff’s connection to the scientific community increases the likelihood that Hawking, even posthumously, may become a part of the ongoing conversation.

Frank & Alicia
They Can’t Stay Under the Sink Forever

The forthcoming spinoff of The Big Bang Theory may not land on CBS, but it still offers opportunities to appeal to long-time fans of the original series. One powerful way to achieve this would be to finally showcase Sheldon’s elusive friends, Frank and Alicia, in a tangible way. Contrary to popular yet misleading fan theories, the Alicia mentioned isn’t necessarily the same person who resided above Sheldon previously, as their interactions were never grounded in friendship.
While Alicia might not fit the mold of someone engaging in Sheldon’s famed game nights, integrating both Frank and Alicia into the spinoff as patrons of Stuart’s comic shop, with acknowledgment of their friendship with Sheldon, would resonate profoundly with devoted followers of the franchise.
