The tranquility lane can get finished either the good karma (short) or the bad karma (long) way. Short way: you go to the abandoned house and do the activation sequence - activate Radio, Pitcher, Gnome, Pitcher, Cinder Block, Gnome, Bottle. Then a terminal appears, read the info on the simulation or straight on go to the Chinese invasion option. Long way: go chat with Betty , you will notice, that there's something wrong with her... Do whatever she tells you to do. For every action you take, it affects your karma, in the wrong way... and tell him that he's gonna have to go there. Sorry kid.
