Pratt is not the only Everwood star who took to social media to pay their respects. Amid news of Williams’ death, Emily VanCamp remembered the “wonderful” moments they shared on set.

“I was always excited for the next time,” she wrote in a June 13 Instagram post. “Sending all my love to your family Treat. Fly high my friend.”

Meanwhile, Vivien Cardone, who played Williams’ daughter Delia on the series, called the later actor her “second father.” 

“My heart is shattered,” she shared in a post of her own. “In a strange new place, surrounded by unfamiliar people, you were the first person who made Utah and Everwood feel like home.”

Williams’ TV son Gregory Smith also opened up about his fondest memories of the star, telling E! News in a statement, “He made an indelible impression on me during my most formative years. I will always cherish my time with Treat and think fondly of his stories, his laugh and his passion for adventure.”

Calling Williams a “wonderful man and a brilliant actor,” Smith added, “I’m very grateful for the time I got to spend as part of his extended TV family.”
