Egon was in the living room setting up the Christmas tree, carefully placing the balls on the green branches of the plastic pine tree while humming a soft tune. The scent of cinnamon from the nearby candle warmer filled the air, mixing with the fresh pine aroma of the tree.

He and his wife would have been married for 10 years that Christmas. A milestone worth celebrating, even by Egon's typically reserved standards. The soft glow of the string lights he'd already hung reflected in his glasses as he stepped back momentarily to assess his work.

That same Christmas, she had a surprise for him. She spent the last weeks hiding this information from him, carefully timing doctor's appointments around his ghostbusting schedule and discreetly researching pregnancy books when he wasn't looking. She'd practiced her delivery a hundred times, wanting to make sure the moment was perfect. She was pregnant. And tonight, beneath the twinkling lights of their Christmas tree, she was going to tell him.
