I know that Grissom can only do so much, but as the boss, he has a bit of a responsibility to ensure that his team's problems don't affect their work as drastically as Warrick's problem's have affected his job. Let me put in this way. In Burden of Proof (Season 2), Sara was about to walk out on the team because she had a disagreement with Grissom. Catherine points out to him that as the leader of the team, people are building a family around him, whether he likes it or not. She says that he should pull his head out of the microscope every once in a while to check what's going on with his team. I'm saying that that is what Grissom could've done for Warrick. He could have seen what Warrick was going through and maybe helped him before things got this bad. He's not their psychiatrist. He knows that eventually they have to sort out their own problems, but he could have made an attempt to get Warrick the help he needed before Warrick had his meltdown. He did that for Sara when she had a drinking problem. He urged her to get help. Why couldn't he do the same for Warrick? I do realize that Grissom has his own problems. It's not easy being left behind and heartbroken, but he did have people trying to help him. Brass, Catherine, and Nick all tried to talk to him in You Kill Me. They were all there for him and willing to help him through his problems, just like he helped them through theirs. Grissom shrugged them off. He has people who want to help him, but he's just too stubborn to accept help. The point I was trying to make in my last post was this: Maybe, after seeing Warrick go through this turmoil, Grissom might actually lift his head out of the microscope and pay attention to the wellbeing of his team. A team can't function if there are problems with one of it's members.
