Vin Diesel opened up about the impact of Paul Walker's death again, so you might want to have some tissues handy.

The "Fate of the Furious" star was at CinemaCon in Las Vegas on Wednesday when the topic of his late friend and former co-star came up. Diesel had touching insight to share of the emotional subject, and he was visibly moved while discussing it, according to Variety.

Diesel, who has been forthcoming about how Walker inspires him in the past, highlighted how much continuing the franchise meant to them all, especially in light of a promise Walker had made.

"It was Paul Walker who promised eight," Diesel said Wednesday. "It played over and over again in my brain."

The cast and the rest of the Fast and the Furious team haven't disappointed. In fact, they're not stopping at eight. "The Fate of the Furious" is just the first in a new trilogy, so we're looking at a minimum of 10 of the car-centric action flicks.

"I always feel like he's looking down on us so we didn't want to let him down," Diesel said.

Fellow franchise star Tyrese Gibson echoed Diesel's sentiments, saying that they "move and operate in the memory of Paul Walker."

Walker, who died in a car accident on Nov. 30, 2013, was a staple in the series. Although he skipped the third movie, 2006's "Tokyo Drift," he appeared in each of the other installments through 2015's "Furious 7," which was in production when he died. "The Fate of the Furious" is the first in the franchise without Walker since his death, but Diesel made it clear that his friend isn't truly absent.

"Part of Paul's legacy lives through every frame that we shoot," he said.

You probably need those tissues right about now, right?
