Alex gets in deeper and deeper with the "Cuban Mafia" and that will surely come back to haunt him. Finding out about Frank's gambling debts and "taking care" of the problem to once again protect his family has once again brought out his dark side. His plan to get revenge on Joe Samuels is going awry because Joe Samuels (blackheart that he is) has stooped to framing his daughter for the illegal Cuban land purchases.
The fact that Isabel and Ellis are becoming friendly is another problem for him in an increasingly long line of problems.
And now, the hint of some mysterious past relationship with Ellis is very interesting.
I love the fast pace of this show which leaves me excited to see the next episode every week.
