At Samburu, the old folks slave away. Lindsey lies around and actually says -- out loud -- "You guys don't mind me not helping." Brandon half-heartedly offers his seat to Linda when she says she wants a place to sit. Silas tells us in a confessional that things at camp are heating up and that "what's being said and what's being done are just totally different things." Silas has gotten, like, a zillion times cuter in one week. Carl and Teresa have a conversation about trusting each other; they agree that they do. Teresa says in a confessional that she really likes the young people, but that if she wants to be on the stronger side, she needs to align herself with Carl, Frank, and Linda. Lindsey says that people on the tribe are always whispering, as we hear Carl say, "Conspiracy." The old group concludes that "Silas is the key." I thought Dawn was the key? Carl points out in a confessional that the younger members of Samburu think being on Survivor is akin to marshmallow-roasting at the YMCA. As the hoary Samburu members go on a water run, Carl summons Silas to go along with them. Silas blows a kiss behind him, and we see Lindsey watching them suspiciously as they leave. Carl explains the alliance to Silas, and Frank tells us in a confessional that they picked Silas because of his strength. Carl says that Silas would be a "complete fool and an idiot" not to stay with the stronger alliance. It'd be hard to be a complete fool and manage somehow not to be an idiot, as well. Carl and Frank use their most crafty techniques to win over Silas, but neither of them says, "Silas, I am your father." Silas looks cute and confused by the proposition; he thought he'd just have to work hard and look pretty afterward. Silas wonders how close Linda's affiliation with the group is and Frank responds, "Linda's so concrete she's buried in the bottom of the Hoover Dam." I've never heard that particular metaphor; it's graphic as far as those things go. Silas tells us in a confessional that "it's a fact" that nice guys finish last. We then see Silas turn to the dark side as he shakes on it and says, "Strength and honor." Various animals pace about and look concerned.
