Poor Scooby-Doo

I know this is random, but I am at a loss.  My son loves the new Scooby-Doo episodes.  He's watching and I'm in the other room listening.  Suddenly, I hear Fred tell Daphne that he loves her. WTF!  I could have sworn that the show was successful when they simply focused on solving mysteries, having guest appearances, like the Harlem Globetrotters(you know you all remember that one), and eating nasty food. Why or Why bring the drama of relationships into it?
