Yup, they have just propably forgot Lee. The point is that he's sleeping somewhere in the audience. Well, I'm also waiting to see what Shino will do. I'm guite sure that he did dispel the genjutsu and is still awake, also he heard about the plan and is still in a good condition as he didn't have to fight Kankuro. Maybe we'll see him fighting in the next episode, I think he is stronger than it seems. We really haven't even seen him a dangerous life or death situation yet, as he dedeated the sound ninja guite easile. He propably has some pretty nice skills.
