Grissom isn't very sympathetic to Warrick's plight, even when Warrick levels with him, mentioning his divorce and the recent disjointedness in the team now that Sara's left. Grissom doesn't react to Warrick's comment about Sara's departure, telling him bluntly not to screw things up at work.
Was Grissom irritated that Warrick used Sara's exit as an excuse for his tardiness, or does Grissom simply think that if he can soldier on in the face of Sara's absence, then Warrick should be able to put his personal problems aside and do his job?
Grissom's mood in the episode goes from irritation to full out anger when he sends Warrick after Warrick confronts the under-sheriff over the warrant for Gedda's office.
