Here's the tv.com episode summary
"Tragedy strikes the McNamara/Troy family after Julia learns what has caused her ill health. A visitor from Christian's past brings revealing news. Sean finds the price of fame to be more expensive than it's worth. "
I think this finale will be the best one since the second season. I hope that they will take this show back to Miami if there is to be another full season. That way, this season will stand out among the others. It'll be the icing on the cake as the most unique season.
