Pinkie Pie is now officially freaking out about Fluttershy forgetting all about her friends. I think going three whole days is a record for her, so maybe she's mellowing out a bit? Rainbow Dash found a way to distract Pinkie from her thoughts (she didn't say how, but I suspect pranks are involved).

Confidentially, I'm a little worried too. It's not at all like Fluttershy to delay sending mail from her destination. She's always thinking about the feelings of her close friends. I'm sending a letter to Cadance, just to be safe.

Oh, and Applejack did some detective work and discovered that some of her missing apples were eaten by the pigs, but she has no idea how they ended up in their trough. I would record how she figured that out, but, well... it's disgusting. Eww eww ewwwww.
