This mission starts at Michael's house. Michael is feeling good about himself after the successful jewelry heist and wants to celebrate. He asks Amanda out to dinner but she blows him off and heads off to her "yoga lesson". Franklin shows up and the two of them have a drink to celebrate as Michael explains Lester is going to unload the jewels and they should have a good haul after paying Madrazo. Dave the FIB agent shows up right after they toast and is obviously worried. He seems pretty certain that Michael pulled off the heist and is worried about Michael popping up on Trevor's radar. Michael doesn't seem too concerned about Trevor and half-heartedly denies being involved in the heist. Dave turns on the TV and the heist is all over the news....
The scene changes to a new location with the same news cast playing and we are finally introduced to Trevor, in his trailer, in Blaine County. Trevor is busy having "relations" with Ashley Butler who is a returning character from The Lost and the Damned, who has a substance abuse problem. The news reporter is interviewing the man Michael bumped into when leaving the jewelry store during the heist and he repeats on the news what Michael said to him "People forget thousands of things each day, make sure this is one of em".
Trevor hears this line and stops and stares at the TV and becomes very distracted and starts pacing around his trailer lost in thought. The scene cuts to outside and Johny Klebitz, the protagonist from The Lost and The Damned, is approaching with Wade and Ron trying to stop him. Johnny calls out Trevor for having sex with his girlfriend in exchange for drugs. Johnny is angry with Trevor but Trevor, lost in thought, ignores him and walks right past him and up the road.
Johnny runs after Trevor and confronts him and Trevor finally acknowledges him and Johnny admits that he loves Crystal and that it isn't right. Trevor softens his tone for a minute to put Johnny at ease and then throws him to the ground, hurls a beer bottle at his head and then murders him brutally by kicking him repeatedly in the head. Trevor then screams at Johnny's body and curses at him about getting in his face and mentions he just saw a ghost (Michael) he then starts walking toward his truck and the cut scenes finally end.
Drive to Grapeseed
When you gain control, get in the truck, wait for Wade and Ron to get in (or on...), and drive out to the location in Grapeseed marked on your map.
Confront Terry, Clay, and the other Lost MC Members
When you arrive, approach the bikers, which will trigger a cutscene. Trevor riles them up, informing them of the events that just took place. They then make a run for it.
Follow the van to their hideout and take out all The Lost
Follow the van to The Lost's hideout. Be mindful of sharp turns in the road as you are giving chase. Optionally, you can kill the two bikers on the bikes (Clay and Terry), which is a requirement for the gold medal, but don't incapacitate the van in any way.
When you arrive, a shootout between Trevor and the Lost will ensue. Go through the hideout and clear out the bikers.
Tip! Use cover and Trevor's special ability as necessary to take out all of The Lost.
Go to Ortega's trailer
After a short while, a few of the surviving bikers will flee. Whether you chase and kill them, or let them escape, is up to you (eliminating them is a gold medal requirement). Return to the truck, and drive to Ortega's trailer, marked on your map.
Push Ortega's trailer into the river
Floor it with the truck into the back of the trailer to ram it into the river below to trigger a short cutscene. Trevor advises Ortega that he controls the distribution of all drugs and guns through Trevor Phillips Enterprises.
Choose Ortega's fate
Have Trevor point his gun at Ortega. From this point, you can either kill Ortega before you leave or leave him alive. Do what you think Trevor would do.
Go to Trevor's Trailer
With the job done, return to Trevor's trailer to complete the mission.
Ron will call Trevor following the completion of this mission to briefly inform him about the prospective drug deal with the Chinese.
