Dear Diary... Who am I?

I asked if it was okay to check out AJ so I could help her, and the doctor said yes. I led her out of the hospital and to the apple orchard. "Where are we now?" she asked. "We're in your orchard." I said. "My orchard? I- I have an orchard? Who are they?" "That's your family; Big Mac, Granny Smith, and Apple Bloom." Applejack walked up to the three ponies standing in the barn. "My... family?" she said.

"Applejack! I missed you so much! What happened to you?" Apple Bloom said, grabbing onto AJ's legs. "To be honest, little filly... I... don't know." Applejack said, then turned toward me. "This Pegasus is helping me remember." "You mean Rainbow Dash?" asked Apple Bloom. Applejack looked at her and said, "I think so."
