Hmmm...I don't know what happened to the first part of my comment. Here it is in short. I'm going with Hodges too. He seems obsessed with Grissom. Everyone besides Hodges seemed genuinely surprised to see him back at the office when Grissom returned. Also, I agree on the little hints being dropped. Hodges was definitely hovering over Grissom last night. And I felt like he was taunting him. Like with the comment about the woman being poisoned. When the woman was not poisoned, Hodges remarked on it, almost like he was throwing it in Grissom's face that he was wrong. I think Hodges wants to outsmart Grissom. I have no clue about Hodges ever being in foster care, but remember the guy from Psycho had a mom too...a skeleton in a rocking chair!
