That's the lesson this episode teaches. You can't always expect to get what you want in life. And the teach this lesson well in this episode. I like that Alex has trouble communicating with her dad, when Jerry doesn't want to lose her little girl. They do that plot a lot, but they really did it great here.
Its also nice that for once, Alex and Justin work on the same side so that Justin can be nice and help out his sister. and thanks to Justin, Alex is great on flying the carpet and her and Jerry are better than ever again. So I believe this episode was really great and kind of touching, and one of my favorites.
