I rather suspect yesterday's episode was the most AJ's dead parents have been on her mind since the family reunion.
And why wouldn't she associate independence with the loss of her parents? You may recall that when AJ was around Apple Bloom's age and getting her cutie mark, there was already a conspicuous lack of parents. It's hardly outlandish to theorize that the loss was one of the main factors that drove her to run away to Manehattan, where she could have ponies one generation older to take care of her and didn't have any major responsibilities weighing on her.
So I can't help but assume that when she thought of Apple Bloom home alone, she saw a little orange filly, forced to grow up quite abruptly. And then she was thinking of losing close family, so is it any wonder she started worrying about Apple Bloom's safety? She was probably checking on "Apple Bloom" so much during her nap because she needed to distract herself from the dark spiral of her thoughts.
But, hey, that's psychology. You want what you do not have, and then you assume others want what you want, and so you give them what they already have too much of.
Exactly what I was thinking.
