it apprears to dr. brian that he has never really had any good stability in his life. be that, be the good friend he never had, show him its ok to be himself he doesnt have to be someone else to be your friend. id say meet him after he gets off work before he heads to the bar and hang out with him show him he can have fun with out drinking. just being there for him is gonna do wonders for him i guessing. (be a friend)
