Young Sheldon has proven to be a worthy successor to The Big Bang Theory, giving fans a glimpse into Sheldon Cooper as a child. But while Young Sheldon is centered around Sheldon himself, there are many other characters who shine. In fact, there are several characters from Young Sheldon who are so likable, some fans wouldn't mind it if they got their spin-off show themselves as they have proven to be quite entertaining and hilarious too.
However, beyond the main characters, including Sheldon's parents George and Mary, siblings George Jr. and Missy, and his beloved Meemaw, there are several supporting characters who are worthy of accolades as well. Hopefully, some of them will continue to feature or make reappearances in the future too.
Brenda Sparks
Just as Young Sheldon improved as the showed went on, Brenda started to grow on fans, too. However, fans haven't warmed up to her completely since they can't completely forget how mean she was to Mary in the beginning. While the two neighbors eventually became friends, particularly after Brenda and her husband got a divorce, Brenda had been previously been quite judgmental of Mary's parenting skills and would often mock Sheldon.
However, as she began to lean on Mary for support, Brenda became more vulnerable and likable. Fans can tell that she really does love her children and only wants what is best for them. Hopefully, this friendship will continue to blossom as fans really enjoy these scenes too.
Billy Sparks
Billy has a good heart, but he's easily the least intelligent supporting character on the show. He's sweet but oblivious, which is both his best and worst character trait from Young Sheldon. He's often presented as the polar opposite of Sheldon, yet he seems intent on being friends with the young boy.
While Sheldon seems to tolerate Billy simply because he's a neighbor and always willing to hang out, and Billy is sweet and kind, there's not really much to him. He doesn't add a lot to any plot in the story and is mainly only there for comic relief.
Mr. Lundy
Mr. Lundy is that teacher every school has who believes he was meant for something more and just ended up teaching because he wasn't sure of what these dreams are.
One of his funniest episodes was when Mr. Lundy took over the Halloween haunted house plans for the neighborhood, trying to control everything as though he were a big-time theatre director and producer. His scenes are often over-the-top, and he's a funny addition to the cast.
June
June is the ex-wife anyone wants to have. She has still got a good friendship with her ex and has even befriended her ex's new girlfriend, Connie. Not only is June happy-go-lucky and fun, but she has also become a good confidante for Connie, who felt comfortable talking to her about anything.
It's June who helped Mary change her hair when she began to rebel and start thinking about herself. June also supported Connie when she needed it, even enjoying a weekend of debauchery in Vegas together. Fans would love to see this friendship develop even further in the future as fans hardly see Connie interact with anyone outside of the Coopers.
Pastor Jeff
Watching Pastor Jeff interact with Sheldon in church is a highlight of the series as he tries desperately to handle all of Sheldon's existential questioning during his Sunday sermons. While he's a sweet and kind pastor, Pastor Jeff sometimes seems lost, such as when his first marriage, which never seemed genuine to begin with, broke down.
He's really the only true friend Mary has, and, beyond their spouses, she might be the same for him. Pastor Jeff's storylines help bring more attention to Mary's religious roots and her relationship to God.
Paige Swanson
Fans loved when Paige was introduced because it was like Sheldon finally met his match: a teenager who was not only as smart as him, but possibly even smarter. She kept Sheldon on his toes, made him jealous, and ultimately brought him back down to reality.
Paige had an interesting arc, as the next time she was seen, she was rebelling, dressing differently, and not focusing on her education. It was all in response to her parents' divorce. Watching what it did to the child was eye-opening and made for one of the saddest moments from Young Sheldon. Seeing Paige's downfall made fans hope she could eventually turn things back around and live up to her true potential.
Dr. Linkletter
Dr. Linkletter's relationship is much like Professor Proton with an older Sheldon. While he appreciates Sheldon's intellect, he is often annoyed by him. But Mr. Linkletter's insistence on trying to get rid of Sheldon is also balanced by his rivalry with Dr. Sturgis and his obvious crush on Connie.
His shining moment included hiding from Sheldon when the young boy started university. It was one of the most questionable parenting choices on Young Sheldon when Mary and George Sr. allowed Sheldon to attend at such a young age. Sheldon was lonely and out of place, particularly without Dr. Sturgis there, and kept trying to have lunch with the professor. However, although Dr. Linkletter continuously rebuffed Sheldon's invitations, he has proven to be instrumental to Sheldon's growth and future success - which is why fans are glad they will be seeing a lot more of him in the future.
Tam
Finding out that Sheldon actually did have a friend, and a pretty close one, in high school, was heartwarming for fans to see since he always spoke about not fitting in and not having friends. Like Sheldon, Tam didn't fit in either, but mostly due to cultural differences since his family was not from Texas but Vietnam.
Tam was also pretty smart and he got along well with Sheldon because of his intellect and how he could relate to being an outsider. Tam's lunch chats with Sheldon helped to humanize the main character as just a kid trying to navigate the typical trials and tribulations of high school.
Coach Dale Ballard
Coach Ballard had a great arc on the show. He started off as the misogynistic baseball coach who refused to have Missy on the team simply because she was a girl, even though she was clearly talented.
After a good talking to from Meemaw, however, Missy was put on the team and Coach Ballard became enamored with Connie. As her boyfriend, he has become an integral part of the story as fans wonder what happened to him between then and now, and if Connie ever did remarry.
Dr. John Sturgis
Dr. John Sturgis made regular appearances on the series for some time but after his mental breakdown and break-up with Connie, he isn't seen as much. With that said, he remains the best supporting character on the show.
Not only is he someone who Sheldon can truly relate to, despite their major age difference, but he's sweet, kind, and helped Sheldon come out of his shell. He's always upbeat and positive, and despite his social awkwardness, his presence gives George Sr. and Mary hope that Sheldon will be able to find love and happiness when he gets older.
