Brick has developed obscure interests, such as his obsession with fonts, whispering to himself, and "whooping." These quirks, labeled "tics" by his parents, are discussed among many of Brick's peers. Because of his ticks and other abnormalities, both Mike and Frankie are subjected to an annual visit with Brick's teacher to discuss his behavior.
Brick's actor, Atticus Shaffer suffers from type IV Osteogenesis imperfecta, also known as "brittle bone disease", a rare genetic disorder directly affecting the skeletal system. It is assumed his character has this as well, but it is never mentioned in the series.
Brick is exceptionally smart, but frequently procrastinates on his schoolwork or just forgets it all together when he does complete them. He tends to isolate himself from classmates. He acquired a certain tick where he shouts "whoop!" in Bunny Therapy. Apparently he whoops when he lies as shown in The Hose. His parents Frankie and Mike call this "whooping". His quirks include obsessions with reading, unusual speech patterns, and difficulty fitting in with his peer group. Brick also whispers words to himself throughout the series, which is known as his first "tic". In a few episodes, Brick was known to have an obscure interest in fonts and he has even created a podcast based on fonts in one episode. He is portrayed by Atticus Shaffer. Brick's strangeness results in his parents, Frankie and Mike Heck, having to attend the annual talk with Brick's teacher. Frankie and Mike also have to attend his social group classes. In these situations, Frankie and Mike try to explain that Brick is not special or weird but in the end Frankie usually admits that he is special.
He always remembers things he reads, such as how to repair a lawn-mower in The Block Party. In the season 2 finale, he mentions to Sue that on days he doesn't read, he can remember quite well. He is very awkward, and doesn't have many friends, but makes friends with an equally awkward boy named Arlo, but struggles to deal with him. Once he reaches middle school he befriends odd children like himself, Troy and Cindy, having a romantic relationship with the latter. Brick is also a brilliant speller and almost won the regional spelling bee, but was disqualified by a strict judge when he whispered the last letter to himself. However, in his second year of the competition, he was eliminated in the first round of his local school competition by misspelling "reindeer", with the classic mistake of spelling "reindear".
Frankie and Mike Heck
Frankie and Mike are always trying to solve more important things than poor Brick. Mike and Frankie both have to attend a meeting with Brick's teacher every year about his quirkiness and attend his social group's meetings. Brick basically reads his life away, and Mike and Brick never get to bond. Mike got Brick into football by having him read up on facts and find his favorite 3-syllable words. Brick began to like football and knows tons of facts; Mike told him that if he could talk sports, he could talk to any guy in the world. Mike and Brick watching football made Axl jealous. When Mike had his buddies from the quarry over to watch the game, Brick talked too much and made them leave one by one. When Brick used the Father's Day coupons he made for Mike, he bothered Mike his whole vacation until Mike told Brick to leave him alone.
Axl is generally a terrible older brother towards Brick by doing things like farting in his face or anything else, but the two have been shown to get along. They both share a room together. There have been times where they have been shown to have a good relationship like at the end of the season 4 episode From Orson With Love where Brick admits to Axl that he will miss him when he goes off to college, however, there have been some episodes where Axl hates Brick like in the Season 4 episode Twenty Years where Axl purposely spoils the ending for the book Brick is reading making him sad. It is revealed in Twenty Years that Brick has no people friends only books, making Axl regret his actions, however, Axl makes it up to Brick by making up a different ending, overall, Brick and Axl have a neutral relationship.
Sue and Brick have a good bond when they have to help each other such as figuring out how to cover up the hole in Sue's wall twice, or Sue trying to sound like Frankie on the phone calling Kevin Siccola's parents to say that Brick can't attend his son's birthday party which she constantly messes up. When Axl had to look after a baby doll for his school homework, he wasn't very good at it, and the baby doll was constantly crying. Brick moved into Sue's bedroom for a bit as he could not sleep with all the crying. Sue and Brick decided to keep throwing objects at Sue's wall next to Axl's room to cause the baby to keep crying to wind Axl up. But their fun turned into a nightmare when the wall started to crack and ended up becoming a huge hole in the wall. They covered up the hole with Sue's posters, but Sue later confessed in an episode of season 2 when Mike came to punish Sue for seeing an adult film with Carly (which Sue already felt bad about and kept pleading to be punished more). By season 4, Sue and Brick bought an old vault from an antique shop hoping there would be a ton of money inside. This caused them to create another giant hole in the wall. It is unknown when the wall got fixed again. Another big hole in the wall was created in Season 8 when Brick and Sue were fighting over Sue's room. Sue had allowed Brick to stay in her room over the summer while visiting Dollywood, but Brick wouldn't move back out after the summer. Sue locked herself in her room, and Brick (dressed as a bowling pin for Halloween) broke through the wall where the hole is always created and created another huge hole. In the series finale, Frankie mentions the hole was never fixed after that.
Brick once admits to a priest (during a "families in crisis" meeting after Mike threw a book at Axl) that he feels invisible, which leads Brick to have a one-on-one. When Brick is supposed to tell his parents what he told the reverend, Brick claims he would rather have wintergreen toothpaste which the family agrees to do. When Brick asks for food (as the family was supposed to go out for dinner) Frankie takes a mint out of her purse and gives it to him. Brick tries it and hates it, and Frankie states it's wintergreen. Brick realizes he doesn't like wintergreen.
