The camera swoops around Tarzan as he rocks back and forth, touching his forehead to his hands. He stops for a second, and looks up quickly with an exhale. Jane sees this. Tarzan takes about two leaps and is suddenly up at the observation window, staring at Jane. They stare at each other, open-mouthed and slightly panting. "Hello," Tarzan says, plain as day. Hysterical. He might have just run his hand through his hair and gone, "Hey, 'sup?" And Clayton makes this face that makes me think that this whole "mute" thing was just bullshit, but I read somewhere that Clayton was supposed to be angry that Tarzan chose to speak to Jane first. In any case, right now I'm voting for Clayton being a gigantic liar, and that Tarzan's been chatty ever since they found him in the jungle. "Hi," Jane says. Clayton hits a button, and a wall comes shooting down over the window. He tells Jane that John's had enough excitement for one day. He backs away, leaving Jane to wander around, still mouth-breathing.
