You should trigger drunk event in the kitchen three times. Follow up the dialog by choosing 2nd option, then follow up dialog by choosing 2nd option again and from now on choose the right dialog options for each of the three scenes: 1) What’s going on? Have I done anything wrong? 2) This was never about Dude. It was about us. 3) Because you’re my Milf and I love you. After third answer you should revisit the kitchen and that's it
