A meeting with Nurse Tenderheart and a chance encounter with a filly motivate Sam to invite Rose over for dinner, as well as to push Sam just a little further into full integration with pony society.
After a day of work in Rose's flowerbeds, Sam winds up spending the night.
Sam's still trying to fit in, and Rose is still trying to help her, but the human and the pony don't always understand each other's culture.
Shortly after their trip to the spa, Sam decides to invite Rose over for dinner.
