When Gaten revealed his condition to the showrunners, they decided to write it into the series. “When they heard that I had the condition… they liked how I told them about that and once I got the part they said they’re going to incorporate that and kind of use it in a realistic way,” he explained. He also mentioned that the directors noticed him stretching and that his shoulders were “touching” when he did it. That is when he announced that he was born without collar bones. Gaten’s character was bullied in the show due to the condition which he was “cool” and “realistic.”
