I want to add that "friends of nikki" is mabye wrong, she is totaly alone, which i find interesting: bear lies about nikki to the other two, and obviously isnt truely interested in her wellbeing. Ian had an affair with nikki but is just interested in her wellbeing when he uses it to shoot against baer who he envies. Sarah is in love with bear and is totally toxic against nikki, victimblaming her. Ok maybe bear is very central in these relationships bur maybe not less central than nikki...
