In a new interview, Paul Walker‘s brothers, Caleb and Cody, recently opened up about how filming Furious 7 helped their grieving process.

“We got to understand more about Paul, and what he was all about,” Caleb told ET. “We had to share Paul with a lot of people, in a weird way. He was gone a lot, he was filming, so we missed him. Sometimes at the holidays he wasn’t always there, you know? He tried. We’d see him on set, we visited a few times, but to kind of get that closure, and understanding [of] Paul was really special.”

“Vin’s like the godfather, he really is,” Caleb added. “We were able to learn some things through Vin, Tyrese [Gibson], Ludacris, Michelle [Rodriguez], Jordana [Brewster]. They all had some really cool stories about him. So, to kind of get that closer and understanding of Paul was really special.”
