I have no clue what impact Sofia has on Scott. I know nothing about her. I only see brief snapshots. But I do know if someone has underlying issues that go untreated it will never get better. Scott never grieved properly when his parents died and for that I put a little blame on Kourtney. She obviously isnt a counselor but she is so damn cold and emotionless. I remember that time she was pushing him to go to the Hamptons home and Scott broke down in teara saying he wasnt ready to face going there. Kourtney with that blank, monotone voice of hers and without even reacting to Scott having a meltdown just said something like "well its time you need to move on with your life". Scott may still have deep issues with his parents death. I cant even fathom losing both in a matter of 3 months. IMO he also needs a long, strict rehab stay. Bad drug and alcohol problems dont go away on their own.
