A one-night stand certainly would have made things a little more interesting in canon!

As for Layla and Yuri, Layla may have retired from the trapeze, but now she's doing Broadway, which can offer her a bit more longevity, and Yuri's helping Kalos with the business part of Kaleido Stage at the end of the series. I still think it's unlikely they would ever have kids, especially considering Layla's issues with her father. I think if she ever did have kids, she'd want to be a stay-at-home mom and really be there for them, but I just can't really imagine her as the stay-at-home sort! *laughs*
