In 2002, Paul Walker and Vin Diesel took home the MTV Movie Award for Best On-Screen Duo for their work in The Fast and the Furious, a movie fueled on big emotions and sky-high ambition. Little did we know of the indomitable bond and the brotherhood Walker and Diesel would form over the years as they strapped into their muscle cars and hit the gas on one of the most successful franchises of all time.

Twelve years later, the brothers would take home that same honor at the 2014 MTV Movie Awards. However, this time it was different. Walker was gone. The brotherhood was broken. In a taped acceptance speech, Diesel said, holding back tears, "I wish he could be here to see this, but I know he's here in spirit."

The following year, however, Diesel returned to the MTV Movie Awards stage in Los Angeles with a renewed spirit. He wanted to honor Walker, or "his brother Pablo," and his legacy with something special -- something unforgettable. So, donning a Fast & Furious T-shirt, Vin sang “See You Again” -- the Wiz Khalifa and Charlie Puth track made famous in the tear-inducing closing scene of Furious 7 -- one last time for his dear friend.

"The last time I stood on this stage, it was with my little brother Pablo," Vin said with a twinkling smile before he belt out an impromptu rendition of the heartfelt song. It was an incredibly raw moment, one that defined last year's show.

"See You Again" was co-written by Khalifa and Puth for the Furious 7 soundtrack, and while the song failed to receive the recognition it so rightly deserved from Hollywood suits, it left an impact on everyone who heard the track play in that movie theater, as we watched Brian O'Connor and Dom Toretto take their final ride together. The song was so special to him, Diesel originally shared the music video on his Facebook page with the message, "Pablo, this weekend you turned the world into a family... Thanks for the love..."

MTV News caught up with Diesel after his emotional performance last year, and he revealed that his tribute to Pablo was actually inspired by his son's obsession with the song. So not only is Vin an incredible friend, he’s also an amazing dad. Last March, Diesel welcomed another little one to the family -- a daughter, named Pauline, after Walker.

It's moments like this that define the MTV Movie Awards as a place where films like The Fast and the Furious franchise, and actors like Diesel and Walker, have been championed. Where brotherhoods are cemented, where on-screen heroes are remembered -- and celebrated.
