it was in the half-cadences when the melody went from vi to ii

At the risk of deflating a joke… 
  
 I had to listen to it to try to figure out what you mean, but I don't find it. Do you mean that the melody goes from scale degree 6 to scale degree 2, or do you mean that the harmony goes from vi to ii?
