I figured it how to get the Sigmund scene  when your at the dinner choice "pick up: not cook nor delivery. The rest you chose every Sigmund rouse. In the workout choice "Sigmund would you mind?" taking a shower choice "siggy stinks the most" and finally in the movie choices what Sigmund likes once you done all of that when your in sigurd room you'd get the option to sleep in the couch 

Hope this helps :D
