Feuds between characters have always been a key source of comedy in most sitcoms. Sam Malone's ongoing rivalry with Gary of Gary's Olde Town Tavern on Cheers was key to the legendary series. Black-ish had its own continuing feud, but this one was between an adult and a child. And to make matters even more complex, the reasons for their enmity were never really explained.

ABC's Black-ish told the story of an upper-middle-class Black family navigating life in Los Angeles. Dre and Bow Johnson had a total of five kids, which included their twins, Jack and Diane. Despite being twins, the duo could not have been more different from each other. Jack was a likable, personable dimwit who knew how to charm people but could barely tie his own shoes. On the other hand, Diane had very little use for people and was both devious and cunning. No one knew that better than Charlie Telphy.

Diane  and Jack make a presentation

Dre worked at Stevens and Lido, a marketing firm owned and operated by white people for the most part. As one of the few Black people employed there, Dre was excited when another Black man got a job there. Unfortunately for him, that person was Charlie Telphy. It's important to note that Charlie was good at many aspects of his job, particularly the ones related to customer service.

The other side to Charlie was the absurd things he seemed to be doing at all times. Despite being a father, he almost always forgot he had a son. The man was a perennial wild card who was capable of anything and everything, someone who added a sense of absurdity to the series it might not otherwise have had. There was a real possibility that it was this absurdity Diane responded to so negatively and with such gusto.

Charlie lays on the charm

Throughout the series, Diane showed nothing but disdain and disgust for Charlie. She threatened his life on more than one occasion, even from a young age. For his part, Charlie was afraid of Diane and always wary while in her presence. Since she was planning to kill him, this was the right call. There seemed to be no reason for her hatred of Charlie, other than his inherent absurdity.

Diane was a serious person, to say the least, and was not given to any type of ridiculousness. The problem for her may have been the fact that Charlie was fueled by pure, unaltered ridiculousness. On numerous occasions, Diane made it clear to Charlie that she did not respect him in the least. Everything about Charlie and how he lived his life seemed to personally offend Diane, which was likely what led to her desire to destroy him. That being said, the ferocity of her dislike was never really discussed.

While Charlie being so strange was great for the show, it obviously irked Diane. It's not hard to imagine that she took the news that he was one of Zoey's professors on Grown-ish poorly. At the same time, this information would have also provided her with yet another opportunity to take Charlie out. Unfortunately for Charlie, Diane was also darn good at creating her own opportunities.
