If you wait until after saving Keith, you can do all three parts of this mission at once, saving you from doing them separately. You start each part by checking the red berries in front of the ship Daisy is trying to repair (they’re flashing).
After Saving Liza
The first event starts with Grant telling some stories. Jason will get up, and Grant convinces him to go buy some drinks, with him paying for them. Go up to the bartender and order some drinks. After a toast, Jason will wake up back in the cave at Earnhardt’s mansion.
After Saving Oliver
The second event has you trying to find where Riley has gone to in the club. Go down the stairs and you’ll overhear some people talking about Americans in the bathroom. If you go on the dance floor, you can dance a little, but it’s nothing special. To find the bathroom, from the bottom of the stairs, there’s a hallway to the right. Go all the way in the back to find Keith and Riley arguing with some people, where you’ll butt in and break it up, waking up in the cave afterwards.
After Saving Keith
The third, and final, event has you starting out on the dance floor, so press the buttons on the screen to do some moves. Some guys will come up and start some trouble, so follow the button prompts to knock the one out. You’ll run off and head through the back door. While you’re in an elevator, the DJ will mention something about an island where you can do anything, going back to the event at the very beginning of the game.
