Thanks guy's, so yes ive completed all quests from River, plus I romanced the dude. I figured it out, wait 24 hrs in game then he messages and says he's missing me! Ahhh, so I click on the quest called...'Come over to my house,' (ive prob. got the name of the quest wrong). But yeah, I sit on the small round stool and click wait for River..& hey over here comes to talk, shower, stands by the window while I sit on the window ledge....then later after a boogie.. sleep when its late, wake up to coffee & a cupcake left by him! The dialogue throughout these ' dates' is the same & limited, but at least the effort of romancing his @ss made it possible to know he's around still. He's phoned me since telling me about his PI career..I chose a sweet name for his agency....
Alas ive just spoken to him for the last time! As in the next 2 hours or less I sided with Haniko & will have to take on Adam smasher! It doesn't bode well....
