I gotta say I'm getting a little sick and tired of Christian's appearances. I want to see Jacob. Plus sometimes they're a little superfluous. Was it really necessary for him to show up and say hey come in this cabin and look at this picture! Couldn't they have just investigated the cabin on their own? Not to mention we pretty much know that Christian is just like Locke... a normal guy who was resurrected by the Island and speaks for Jacob but isn't mystically knowledgeable himself.
