Given your past adventures with LJ, caution may be warranted ;-)

You could consult with said uncle who might have an opinion and could also consider that the cousin is using an email address that ends in "_hottie" when writing to her uncles, aunts and grandparents. She may (or may not) be more worldly than you remember ;-)

I was also watching NCIS the other night, but I'm not about to friend you on facebook, so don't get too creeped out...
