I wouldn't worry about what your friends might have found. There is nothing you can do about it anyway. Most likely, anything they found wouldn't make much sense to them anyway.
I'm sure you're right, it's just that my friend's fiance is kind of a big gossiper and has a big mouth, and she might just say something to W if she did in fact see something that raised her curiosity. I'm hoping against it, but you are right that there's nothing I can do about it anyway.
