They return to the sitting trot and establish a more consistent contact to the bit.  Lars explains that she cant be light until she is through and encourages the rider to keep a soft, rubber band feel with the bit. When they go to the canter he helps her push through the resistance to find more throughness. They take a walk break and Lars has her reestablish the feel and work on keeping it before going to the sitting trot. He challenges her with the shoulder in while keeping this feel.  When they change directions to go right again they try using a bit of counter flexion to help establish the connection.
