it's some kind of file or something with evidence. He's explaing to Kate that the link that killed these people are the same kind of link that killed Nick's old partner before her....so he's sad. Plus he was grossed out and freaked out by the crime scene, kind of like the boiling head scene he had on csim. He actually said almost the same line he used on csim on ep "identy" he said something like " I didnt sign up for this, this wasn't in the job discription." SOme thing like that. I'll have to watch both again later to get the exact wording, but when he said that it reminded me of that ep...
