5. Graveyard Stand-Off
The penny finally drops for Trevor and it's entirely probable that he had an inkling where Brad was all along and just didn't want to believe it. It's the point that the game has been building to since the start; a major fallout between Trevor and Michael that's all about that prologue mission 9 years prior. Brad's character is not exactly one we got to know - indeed, his only credit was getting shot - but it was clear that this guy was really important in Michael and Trevor's lives. He was the third, a space which Franklin now inhabits, and Trevor's fury shows his bond with his heist partners, actually demonstrating a very human side to him. Say what you want about Trevor, but he knows family. Michael's betrayal (him faking his death and living his life in luxury) cuts deep, and Trevor reacts in a very real way. He gets angry. Less real was the digging up Michael's grave to see Brad's body for himself; the scene is tense and especially enhanced by Brad's decomposed face chirpily looking up at Trevor.
