The game didn't find a bigblackcock for Christine to sit on... j/k
I'll take a look and see what it says in the script..
@FXM... here's the solution
IF you chose to have Christine not go with you to meet Silver, it's defined as -
BigBlackCock = 1
IF you chose to have Christine got with you to see Silver, it's defined as -
BigBlackCock = 0
Enable console and enter the route you chose.
EDITED... read variable wrong at first and when double checking, found the trigger. It's on day 5. Sorry! It is verified now.. it's Day 5, the choice of subway or go with MC to see Silver after the shopping trip.
Original variable is set as 0. It stays at 0 until you tell her to take the subway home instead of meeting Silver. When that happens, it triggers the change to 1.
