It's no secret that Vin Diesel and Paul Walker were close friends. In fact, they were so close that Vin even gave Paul a nickname: Pablo.
Vin has said in interviews that he came up with the nickname because Paul reminded him of a character from The Godfather movies named Pablo Escobar. He also said that he used to call Paul my brother because they were so close.
Paul Walker tragically died in 2013, and since then, Vin has paid tribute to him in various ways. For example, he named his daughter after Paul and got a tattoo of his friend's name on his arm.
It's clear that Vin misses his friend dearly and continues to think about him often. Pablo will always be remembered fondly by those who knew him best.
