What happened on Army Wives tonight?

I need my army wives fix. What happened tonight? What is going on with Micheal Holden? With Emmalin? With the fiancee, Tanya. I kinda figure that she is pregnant after all. I also have an idea about what is going on with joan and Roland and their foster son. But MIcheal, Emmalin, and Tanya are all I want to know about.
