Brothers have such a special bond.
So Paul Walker's death has been especially hard on his younger brother, Cody.
He's been coping with the star's passing by throwing himself into all of Paul's passions.
First, he and his other brother, Caleb, served as Paul's body doubles to finish up Furious 7.
Now, he's continuing to keep Walker's legacy alive by serving as the brand manager for the actor's disaster relief organization.
Paul left behind Reach Out Worldwide after his fatal car accident in 2013, and now Cody is taking the reigns. He explained:
"Aside from acting, his daughter and ROWW were the most important things in his life, hands down. He was very proud of ROWW and the incredible people he had surrounded himself to make up that team. I'm just doing the best that I can to keep his vision consistent."
Even though there was a 15-year age gap between the two brothers, Cody feels Paul was a "really great example" for him.
He started ROWW it 2010, after an earthquake rocked Haiti. And today, with the focus on the devastation in Nepal, keeping the organization going is more important than ever for his family.
"Paul would have jumped on a plane and asked questions later, and been there a day before we were there. That's who he was. He was fearless."
Cody didn't feel fearless, however, when he first took over ROWW.
He explains that money was tight, and they weren't quite sure, at first, how to keep it going.
"After Paul passed, there were a lot of unknowns … because Paul was such a huge factor behind it. He was the sole contributor. He just paid for everything."
Cody says that his involvement with ROWW was Paul's best-kept secret, because he "didn't ever want any recognition for it."
But now that the cat's out of the bag, the organization has received tons of support from all of the Fast & Furious star's fanbase.
Thanks to his brother, Paul's philanthropic prospects will live on.
