Shortly after news broke of Diamond’sdeathon Monday afternoon, Lopez, 47, spoke withVarietyand opened up about how learning of Diamond’s death has been “incredibly hard to process.”

“From when I found out he was sick to his passing, it’s been incredibly quick. It’s so fresh, it’s incredibly hard to process,” Lopez told the outlet. “And it’s shocking because he was so young; he was only 44. I honestly thought, ‘There’s no way [he won’t make it]. It sucks, but he’ll bounce back.”

Diamond’s rep previously confirmed the news of his death to PEOPLE in a statement, saying his death was “due to carcinoma.”

“He was diagnosed with this brutal, relentless form of malignant cancer only three weeks ago,” the statement read. “In that time, it managed to spread rapidly throughout his system; the only mercy it exhibited was its sharp and swift execution. Dustin did not suffer. He did not have to lie submerged in pain. For that, we are grateful.”

“We shot a lot in the summer time, so it was a lot of juvenile, silly, fun antics stuff that we’d get into,” he said. “I thought he was a funny kid. I liked to have fun and he was like my side-kick.”

Noting that Diamond “was an integral part of the chemistry and the comedy” of the NBC series, Lopez added, “I don’t know if it would have worked without him.”

“We were really hoping he’d make an appearance on Season 2,” Lopez toldVariety. “Now I’m really going to push for some sort of tribute. I would love a whole episode dedicated to some of his most iconic moments or something like that. We have a lot of very creative minds who can try to figure it out, but I haven’t had those conversations yet.”
