John Halbach, who plays the heterosexual Ian, is married to Kit Williamson in real life.
Constance Wu's character was slowly removed from the series after her large involvement in the first season due to her commitments at ABC not allowing her to work on the series in a large capacity while she was under contract for her role in a sitcom on the network. In 2019, after the final season had premiered, Kit Williamson stated he had actually written alternative episodes for each season after the first with more involvement from Constance, but ABC would not allow her to participate.
In every episode of the series, a character wears a piece of plaid clothing.
