Grissom was at the lab finishing up on a case and Catherine was out in the field with Sara and Greg.
Sara was taking pictures when she suddenly felt very dizzy.
"Sar- you ok"? Greg asked kneeling beside her.
"I'm fine, just a little dizzy". Sara replied smiling grabbing Greg's arm as he helped her up.
Greg looked at Sara with a worried look.
"Thank you Greg, really I'm ok". She reassured him.
Catherine had noticed from afar that Sara had another dizzy spell her 6th one in 3 days.
"Well, I think we have everything". Catherine called out to Sara and Greg.
"We're all set too". Greg replied.
They headed back to the lab and Catherine looked at Sara with a concerned look.
Sara knew that Catherine had figured out what was wrong and she would have to speak to the senior CSI once they got back to the lab.
They pulled into the parking lot and got out. Greg went inside to finish things off with the paper work and Catherine and Sara talked.
"Sara, you need to go to the doctor".
Sara couldn't hold back her tears or anger any longer. "I've been in remission for over a year and it decides to come back when I'm pregnant? DAMMIT"! Sara said kicking the waste receptacle that was outside the lab doors.
Catherine hugged the young woman who had become her best friend and who was to be matron of honor in her wedding.
"I can't tell Nick, at least not right now- - I want to make sure that I'm out of remission before I say anything".
Catherine nodded as if to say okay.
"How did you figure out that something was up, other than the fact that you're a CSI"? Sara questioned.
"I know that you like to nurse JT when he won't sleep, and when you didn't nurse him the other night at the cookout, I had the thought run through my mind. That or you just decided to stop nursing altogether".
Sara gave Catherine a sad smile, "I wanted to nurse JT, but I've been throwing up because of the new baby and I haven't had the strength to nurse for very long".
"How about I take you to the doctor"? Catherine suggested.
"I'd like that I actually made an appointment for today". Sara replied with a small smile.
