Trekking through the jungle, Charlie is, and I know you won't believe this, whining to Eko about how Eko got him into a lot of trouble with Claire, "so thanks for that. Hope you're happy. Oh, that's right, you don't do happy." Does he do whiny weasel? Or is that exclusively your territory too?
So anyway, they stop by a tree, and Charlie's all casual: "All right, well, we're here. I found it right here, right by that tree." He's clearly lying, and Eko calls him on it. "You know what? I don't even know you. You asked to see where I found it. This is where I found it. We're done. Have a nice hike." Charlie starts to walk off, but Eko grabs him by the neck and flings him up against the tree, which if I were running this show would happen every episode. "You did not find the statue here. Take me to the plane," Eko says menacingly.
Back from commercial, Charlie and Eko are hiking. "How'd you know about the plane?" asks Charlie. "It's old, you know. It's been out in the jungle for years. Of course, you would know that. You know everything." Eko ignores this, and instead asks why Charlie lied to Claire. "You told her you did not know what was inside the statue." I wasn't lying, says Charlie. "Then what is the wrong idea?" asks Eko, and Charlie, being a twit, has no idea what Eko's talking about. "When I showed you the broken pieces of plaster, you said you did not want her to get the wrong idea. What is the wrong idea?" Charlie glares at him, and starts yelling that he doesn't have to tell Eko anything. "You come traipsing across the island and what, suddenly now you're in charge? You want me to take you to your plane? You best start treating me with some respect!" Thankfully, Charlie's interrupted when something behind Charlie catches Eko's eye. It's the infamous black smoke whizzing through the brush. Charlie wants to know what Eko saw, but Eko just says, "Let's go." Hard to tell, but it looks like maybe that's not the first time Eko's seen the smoke.
