Can anyone fill me in on the first half hour???

You really didn't miss anything the first 30 minutes the action really happened towards the 2nd half. Christopher is upset because Paulie is cutting him out of the action and disrespecting his father-and -law at the same time. Christopher tried to talk to Tony about it but Tony just blew him off and told him he is not advancing in his career because he is never around. Christopher got mad and beat up Little Paulie and threw him out of the window because he was responsible for stealing from his father-in-law. Christopher wanted to prove he was one of the guys so he got drunk with them but was upset when they started making fun of him and his daughter. AJ ran into his ex girlfriend and started crying again. He became really depressed because of their breakup and quit his job at the pizza place because he saw a couple kissing and it made him start crying. Tony is depressed and blaming himself for AJ's behavior because his kid isn't normal and he thinks he passed his depression and mental problems onto his son. Tony also talked to the feds and gave them some information about the Arabs/terroist situation in exchange for a lesser sentence if he is ever caught and facing conviction. Christopher is losing it because he was in love with Adriana and he sacraficed her for his job. I think part of him regrets doing it because he hasn't really been happy sense outside of having a child. I think Christopher is going to get in some serious trouble for killing that guy because he didn't even clean up or dispose of the body. He just left it there. And with him being so angry with Tony and so unhappy with his life who knows what will happen. I can't wait! :)
