If you have siblings, then you probably appreciate the relationship between the Ferengi brothers, Quark and Rom on Deep Space Nine.
Rom's often-naive outlook drives Quark mad, and Rom has a deep affection for his brother, even when Quark uses him. So sit back and revisit 3 times Quark and Rom made siblings all over the world say, "I can relate!"
1. Rom tells Quark the truth about their father
Sometimes, older siblings in the family have an idealized version of a parent that they refuse to let go of. In "Family Business" (S3E23), Quark and Rom discover that their mother, Ishka, has been arrested on Ferenginar for earning profit, something Ferengi women are not allowed to do. The brothers go to visit Ishka, and Quark complains about Ishka's actions and can't believe a male didn't help her with the business dealings. Quark's memories of his father paint him as a successful businessman, but Rom, the younger sibling, brings home the truth.
Rom tells an amazed and angry Quark that because he left home the moment he became an adult, Quark never knew that their father was actually a failure and "went from one bad deal to the next" and that "he couldn't keep latinum if you sewed them in his pants!" This leads to a brawl between the brothers that Ishka has to break up.
Later, Quark bribes Brunt, the Ferengi liquidator, with some of Ishka's profits, and this keeps her out of trouble. This act is likely his acceptance of who his father was and who his mother truly is. It was probably difficult for Quark to hear the truth, but younger siblings often see sides of their parents that older kids don't.
2. Rom standing up for his parenting style
When siblings are old enough to have children of their own, this sometimes creates rifts between them. There's competition as their kids reach milestones, and sometimes other siblings think that they know best for everyone's kids, especially when the youngest starts a family.
In "Heart of Stone" (S3E14), Rom's son, Nog, is eager to join Starfleet. Quark is disgusted by this choice, as there's no profit in being a Starfleet officer. Commander Sisko is suspicious of Nog's motives, but then Nog tells him that his father's engineering talents are wasted because, as a Ferengi male, he must always chase profit, and that he wants better than that for himself.
Quark continues to berate both Nog and Rom about Nog joining Starfleet, but then Rom tells his brother that he supports his son and will always make decisions for his family. Rom standing up to his older sibling on behalf of his son makes us realize what kind of courage we have when it comes to guiding our children.
3. Quark sells Rom the bar
If you have siblings, you've probably watched them do stupid things, like burning bridges with a current employer because they're sure they have another job lined up. Ferengi siblings are no different, as is obvious in "The Dogs of War," (S7E24) when Quark sold Rom his bar because he was certain he'd be chosen as the next Grand Nagus--only it didn't turn out that way.
When Grand Nagus Zek and Ishka arrive at Deep Space Nine, Quark is ready to take on the mantle; however, Zek chooses Rom because Ferenginar is changing, and they need a new type of Grand Nagus. This leaves Quark without a home because he'd sold the bar, at least until Rom hands it back free of charge. Blood is thicker than latinum, at least for Rom, who finally accepts Zek's offer.
Quark and Rom's relationship is incredibly relatable if you have your own sibling drama (like calling your brother or sister an idiot and then kissing them on the head). These Ferengi brothers hardly ever see eye to eye, but there's no doubt they'll always have each other's backs.
