Kelly Jo, Erin, Carson and Tori head to Chicago to visit Michaela and Brandon and take in a few sights. Will culture shock set in for "country girl" Erin, as she explores new terrain in the big city? Meanwhile, back at the Bates house, Carlin, Josie and Katie are on babysitting duty while mom's away. To help pass the time, the kids split up in teams, and have a contest to see who can make the best homemade ice cream flavor. Since Katie's an ice cream fanatic, she volunteers to pick the winner! And later, it's an emotional moment for the sisters, when Michaela confides in Erin about her challenges with getting pregnant.
