Does Greg Sanders from CSI like Sara Sidle?

My sister and I have recently become interested in CSI. We were
watching a rerun of an episode from one of the more recent seasons
(Season 10, I think), and I thought I saw something... But I kept my
mouth shut because I thought my sister was going to make fun of me.
Well, that is until my sister blurted out, "Does he like her???" And
that's when I said, "I thought that too!"

Maybe we were just seeing things. I don't know.

So does Greg Sanders like Sara Sidle? Has he in the past? Does he in
the present?
