A Total Eclipse is headed directly over Rocky Top, TN! So before the big event, Brandon gives the Bates kids an interactive science lesson, demonstrating how the moon blocks the sun during an eclipse. And later, the Bates family gather together at a pool party for some fun in the sun and to marvel at the dark sky above, caused by the Eclipse. And before Michaella and Brandon head back home to Chicago, they meet up with Dr. Vick for a consultation, as they continue to search for answers about their infertility struggles.
