I feel bad for Steven. He seems like a real nice guy when he's not using. Steven clearly has some issues that go beyond drug use that are more than likely affecting his chances of sobriety. Seth on the other hand. Well, he seems to have loved the attention he got every time he screwed up. Maybe if everyone just said you know what we aren't going to play into his games then he may not have been so likely to act out.
I hope Rodney really does well. He seemed to be very serious about the whole process and truly want to do good. He was also very logical on knowing what it took to gain that sobriety. Like giving up the nightlife.
Also, I thought it was very inappropriate for the house manager to do the drug test in front of other roomies. Letting the roomies know what's going on so as to protect them and also as a way to hopeful get the added support for Steven is one thing but to do the test like that just seemed inappropriate.
