Surprisingly, I think Will's the only soap kid on there right now who isn't TOO far off in actual age. I mean, he was only born like a year after Belle, if not before her. Sami's probably, what, like 27? 28? She had him when she was a teenager, and jealous of her sister and mad at her mom for fornicating with John (when they conceived Belle), so Lucas cheered her up by doing her right nice.
