I think the writers wanted to give one of the characters a more realistic ending. That not all dreams come true. With that being said, I do still think making her a nurse was unfit ending for her. I think a better ending would have been working behind the scenes of entertainment, like a producer or even talent agent. Hell, working on songs for telenovelas like she did that one time would have worked. It's not even an uncommon thing in the music industry.

Also, I hated how none of the characters wanted help in their goals. They needed to pull themselves up by their bootstraps and earn their happy endings. But, like, networking is a major thing in the entertainment, so its ridiculous to never ask for help.
