The only way I can see this story line comes to a conclusion is that Rosa’s uncle makes an appearance and have a heart to heart talk with Rosa. Since he is a successful surgeon, he should be able to send Rosa and Gunther on to their respective universities. Rosa focus on her degree so she can join the peace corps and Gunther a possible change in career to become a successful plastic surgeon in his own right thanks to an eye opening experience in Peru!!
I KNEW IT!!! LOL!! And I have a feeling neither did Luann! :-)
