Lucy

Lucy is Natasha's daughter and the Chrissy's sister. 

This small woman is a brilliant engineer, and if it wasn't for her attitude (she's right, she knows it, and she doesn't have the patience for her less intelligent colleagues to figure it out), she'd be the head of her department. Fortunately, her boyfriend Al (who she loves to pieces) is an extremely sociable piece of arm candy who's been smoothing things over at her office events. 

Despite the fact that she'd rather be sitting on a beach solving math problems, she's a fierce and loyal friend.

In fact, she's just plan fierce. Watch out for that tiny left hook! It doesn't have any power behind it, but it still stings.
