"You said you’d be back before I knew it, that I had to be there to look after the farm, and look after Granny Smith. You said you’d be back before I knew it…you promised me…so…where are you? It’s been a year since I asked that."

It has been a year since Applejack's death, and only five months since Granny Smith passed away. Apple Bloom has been feeling the worst of it, even though every pony is trying to help her, she keeps pushing them away.

It's only till one venture into the Everfree changed everything for her and the rest of Ponyville.
