Same as most fans of QAF, I did not like the ending of it since B & J was in love but they could not be together at that moment. However, I understand why it had happened since Justin might be hate Brian in the further if he did not try to work on his career. He loved Brian but he still was a man, thus he needed to be success (at least, trying to be success). It was quite important for a man.
P.S. : for 11#: Brian was the one who said that he had two babies in the next day morning of Gus was born.
