Sara and Grissom?

[hue126.livejournal.com]

I seem to recall in the rumors for last season that there would be some kind of romance between Sara and Grissom. Now, I know I haven't watched the fourth season in its entirety, but other than the moment when Grissom asked to take Sara home after she got caught in a DUI, did that romance materialize at all? Or will the writers continue teasing the viewers with the whole "romantic chemistry" thing between Sara and Grissom?

Everyone's thoughts are welcome.
