And with this episode, we finally know what Fluttershy's family is like (which now leaves only Rainbow Dash with at least some mystery to her family). Her parents are both rather similar to her (or at least what Fluttershy was like way back at the beginning of the series) particularly in being very kind, soft-spoken, and almost no assertiveness. Her brother Zephyr Breeze on the other hand is rather arrogant, obnoxious, sloppy, completely ignorant of the feelings of others, and basically a compulsive quitter.
Since Rainbow Dash has been best friends with Fluttershy for a long time, I knew she had to be already familiar with her family, though based on the conversation with Pinkie Pie and Applejack, it seems the rest of their friends are also at least somewhat familiar with them (unlike the case with Shining Armor when he first appeared on the show).
(I'd like to point out that I had totally hoped that Fluttershy's brother would be younger than her, and I'm glad I was right. Among the rest of the main cast, we've already got dynamics of older sisters, younger sisters, and older brothers, but not a younger brother, so I think it's great that all the bases have finally been covered, so to speak.)
Now for the episode itself. It seems that Zephyr Breeze has moved back in with his parents many times before already, since everyone involved seems to regard it as a usual occurrence. What finally changes things this time is Fluttershy's character development combined with some advice from her friends. And when Zephyr moves in with Fluttershy, she understands right away how much a problem this is, and immediately asks some of her friends to help out. They each give him a very simple task, yet he somehow makes excuses to not do them (though we never really find out what super-simple task Rainbow Dash had tried to make him do at Wonderbolts headquarters). Speaking of Rainbow Dash, I liked the running gag where Zephyr Breeze is somehow convinced that Rainbow Dash is smitten with him, but we can all see that's clearly not the case. I had not expected a song to be in this episode, but either way, at least now Zephyr Breeze is finally starting to take his first steps to improving himself (though he still needs to work on finding a home for himself).
On a more personal note, I must confess that I currently still have trouble figuring out what to do with my life, so I was particularly intrigued after first reading the synopsis how this episode would handle such a subject. Even though I understand some of my flaws, I will say that they are nowhere nearly as extreme as the case with Zephyr Breeze. I may be rather hesitant about working on new tasks, but at least in my case, all I really need is a bit of guidance to get me started and I can handle the rest on my own. I'm not sure if people as ridiculously lazy as Zephyr Breeze actually exist, but either way, I guess I'm a little relieved that, as bad as my shortcomings may be, they are nowhere nearly as terrible as they may be with other people.
