Peter certainly needs counseling, and so does Jason, especially if Peter won't get it.
A, the attack on Peter also traumatized Jason, so he should get some help.
B, staying in a relationship where one person needs help and is resistant means the other needs counseling to manage issues in the relationship.
C, first Barbara's reaction, though repented, and now Uncle Ray's resentment and hostility, as well as the continuing effects of being gay in the public eye, mean Jason's own issues need some attention.
IMHO.
