First, let me say I love Laurence Fishburne's roll. I wasn't sure I was going to like it as much with the Grissom character gone but it really works with Fishburne as part of the ensemble cast.
Second and my primary reason for mentioning it, last night's episode, Miscarriage of Justice, (very) briefly touches on infertility. In this episode, a congressman is accused of murdering his mistress. It turns out that the wife killed the mistress because with the "help" of the congressman, the mistress passed her chlamydia on to the wife which caused her to have a miscarriage. To add to the heartbreak, the wife mentions that she is 40 years old, that they had been trying for 3 years, and this destroyed her last chance at motherhood. No, they didn't mention a lot about infertility but I do think they conveyed some of the heartbreak surrounding it.
Did you see the show and what did you think about how they used infertility in the backstory?
