She has to think about the future of her child, so she might start making more long - term plans, both in her personal and professional life.
Sara may also develop a stronger sense of community. She realizes she can't do everything alone during this time. So, she may lean more on her friends and colleagues. This could lead to new relationships being formed or existing ones being strengthened in the fanfic world.
One common plot point could be how her pregnancy affects her work on cases in the White Collar world. Maybe she has to take a step back from some dangerous investigations for the safety of the baby. Another could be the reactions of the other characters, like Neal might be extra protective of her.

Sookie's pregnancy would likely make her more cautious. In the True Blood series, she's been rather fearless, but with a baby on the way, she'd have to think twice before getting involved in dangerous situations.
