What can I say? How can I explain this? Will they understand? Explode? Question?

I start slowly. I am leaving the lab. Effective immediately. Why? Here goes nothing.

"What do you mean you're leaving? Why? What happened?" Sigh! Catherine and all her questions. There is no easy way to answer. Not in her books anyway. Whatever I say she will make into a saga about her. How SHE never saw it coming. How I didn't confide in HER. How I betrayed OUR friendship (we're friends?). Take a deep breath Sara, calm now, start!

"I know this seems out of the blue but it's not. Lots of things have been happening that you may not be aware of. This is not a knee jerk reaction. This has been coming for a while"

"Knee jerk? Reaction? It has to be! Why are we only finding out now? You could have told me?

See, its out. ME. No care about the others that I have kept this from as well. ME. Get a life Catherine. Oh I am sorry, I forgot – you are the only one that's allowed one. Not that you have handled that one in any great way. Lyndsey is a nightmare to put it mildly. You need to start listening to her. And looking! Where on earth did she get that make-up she's wearing from? She looks like a hooker, and not a high-class one either.

Another deep breath! "Do you want the full story or just the here and now?"

"I think we are entitled to the full story, don't you?" He speaks. Maybe this will let me off the hook. Maybe not! Griss looks at me with a twinkle of amusement in his eyes. He knows what I have to say. Or at least thinks he does. After all, he has known so much about my life over the last ten years it seemed weird not including him in the monumental changes that have happened recently. Poor thing, Catherine is going to kill him once he lets it slip and she realises that he didn't tell HER earlier.

I glance over to the boys. How I love them. They are sitting there like brothers listening to how their baby sister lost her cherry. Nick looks as though he could kill someone, Warrick is in full agreement. Greg, ahh poor Greg, he just looks confused.

"You can't leave, I need you" he pipes up.

"Greg, I am not leaving Vegas, just work. You will still see me around and you can call."

"Not the same" he huffs. But it's not about him either. How can they not get this? Here I am making a decision about me and mine, and all they can think about is themselves and how they have to deal with everything on their own. I haven't even told them WHY I am leaving yet.

I swallow. Deep breaths are no longer working for me. I watch everyone for a moment before beginning again. Cath is throwing daggers my way, Nick looks genuinely hurt, Warrick confused, Griss bemused. I can't look at Greg. I want to burst out laughing.

I blame the hormones and start. "I'm pregnant!" OOOOOKAY. Not even Griss was expecting that and from the looks I am getting I need to explain further but can't. I am laughing way too much for that. Their faces are beyond pictures. I am envisioning a huge canvas in oils, everyone with the same look on their face. SHOCK! Maybe I shouldn't have started this. Maybe I should have waited for backup!!
