Overall, I thought this season was a lot stronger than the first! You've addressed a lot of the criticisms I brought up in my review thread and really gone in for it with a continuous story and addressing the harder emotional issues rather than shying away from them to focus on fluff. The discussion of depression was sensitive and real, and I liked that the stigma of men struggling with mental health issues and macho culture encouraging them to shrug it all off instead of seeking help was addressed.
As for R... well, she's flawed, but I personally wouldn't call her "toxic". Yes, she comes across as an emotionally needy person, BUT she's being nosy with a person who actually really needs that, because everyone else is encouraging him to change who he is and push down his pain in order to be accepted, and R comes along and quite forcefully keeps asserting that she accepts and loves him. Is it for slightly selfish reasons because she also needs validation and attention and love? Quite possibly, but that's just human and it's clear that she is investing effort in a guy who really, really needs it right now.
Having a lot of friends with depression, I've found that you do need to go and seek them out and check up on them and push them a bit to socialise and stuff because they do need it and often self-sabotage and try to destroy or not maintain relationships as a defence. They're generally pretty thankful in the long run if you don't let them run and burn all their bridges or fade away. Sometimes you have to chase friends with depression, and sometimes the people who will chase them are a bit needy themselves, but maybe that's not completely bad?
