Big Macintosh has been in a relationship with his marefriend, Rainbow Dash, for a few months now, and the two are very close with one another. Mac knows that Rainbow does like to have space every once in a while, but when after almost an entire week goes by without any word from his marefriend, he begins to get worried.
Heading over to her house, Big Macintosh finds Rainbow terribly sick, and he knows that he has to be by her side until she gets better again.
