Applejack is a hardworking pony, it’s in her nature, but a cruel trait that comes with her hardworking is not worrying about herself. If she takes on too much work, she will overwork herself. This case is a little more severe than the others. After Apple Bloom falls ill and Big Mac is on a vacation, AJ is left to all the weeks work on the farm while also caring for a sickly Apple Bloom. This becomes very evident when she tries to hang out with Rainbow Dash, but ends up passing out from exhaustion. Dash, concerned, wonders what to do.
