Plenty of television shows love to portray a forbidden, or almost forbidden, romance. It adds to the stakes and forces the audience to either root for or against it. While many romances in television shows are controversial, some cross lines in ways that are a little too familial. While not every showutilizes incest to the degree ofGame of Thrones, plenty of shows advertise teenagers and their single parents dating simultaneously. Although not every relationship ends up working out, it suggests that the kids in that circumstance could end up being step-siblings one day. Sometimes, a previous affair between parents has led to the teenagers in a relationship sharing a half-sibling.
Many shows find loopholes in such storylines to try to avoid issues. InThe Flashcomic books, Barry and Iris never grew up together in the same house, which is a massive change from the television iteration, where they were both raised by Joe from the age of eleven. InThe Originals, Elijah falls for Hayley while she is pregnant with his brother’s child. InThe Fosters, a series about found family, spreads out into a forbidden romance between foster siblings Callie and Brandon. Sometimes, there are ways these shows and relationships could have avoided potentially awkward or uncomfortable situations.

10The Flash - Barry and Iris
The Flashtries to make it as direct as possible that childhood friends Barry and Iris are not brother and sister. They may have grown up together in the same house, but Barry and Iris only describe themselves as friends. Their relationship eventually turns romantic, andBarry and Iris become the most significant dynamic inThe Flash.
Barry and Iris Grew Up in the Same House
Even though the comic book counterparts of Barry and Iris did not grow up together, not all television fans could get behind Iris and Barry’s romance when, at times, it felt that they had been raised as siblings.The Flashcould have gotten around this by creating another character for Barry to live with while he and Iris remained lifelong friends. Even though Barry’s love confession states that he had a crush on Iris before he moved in with her, when looking at how Joe views them both as his kids, and Joe’s father-son relationship with Barry, it may have made Iris and Barry’s romantic connection difficult to get behind at times.

Everything about Betty and Jughead’s romance was fine, up untilRiverdalerevealed that FP and Alice had a child together. The introduction of Charles suddenly makes Jughead and Betty’s romance awkward. Additionally, at one point, Jughead and Betty are living in the same house with their parents, FP and Alice, who were also dating at the time. No one ever addresses how uncomfortable that would be or how likely it would have affected any of these relationships.Riverdaleacts as if Charles is Betty’s brother and Alice’s son, and rarely ever addresses that Jughead and FP are Charles' biological family too.
