Lily couldn't have imagined a better reaction to her news, from the dropping of the cake to the expression on his face. She wasn't typically the one who ended up surprising him, or anyone really. There was a sense of pride in her eyes at having held the information in for as long as she did, considering how much she had wanted him to know.
Giving him a quizzical look at his question, she almost wanted to shake him for thinking she would joke about such a thing. James obviously didn't understand just how important this was to her, if he thought she'd try pulling his leg like that.
"Did you really just ask me if I was joking, James?"
Letting her jaw drop open, it was all Lily could do to keep from laughing. She wasn't going to drag things out now that the cat was out of the bag in a manner of speaking...
"We're having a baby!"
If Lily smiled any wider at James she was sure that her cheeks would kill tomorrow, but it was hard for her to reign in her giddiness over the situation, wanting James to hurry up and get on her level. "I know it's sooner than we expected... I blame you for that."
