The wait is over! The newest chapter in the Lost story begins tonight. To celebrate, we're hosting a live chat during the Lost season four premiere (9pm ET). It's a great opportunity to discuss the episode with fans and share your opinions with other TV Squad readers.

The chat will begin shortly before the show starts. A link to the chat will be provided in the recap post, so check the front page later tonight to join the conversation.

Take it from someone who has seen the premiere in advance--you don't want to miss this episode. It is just as exciting as the season three finale, and you'll want to talk about it with your fellow Lost fans in real time as the drama occurs. See you tonight!
