Charlie looked good -- jeans, but with a jacket (no green linen shirt -- I think he's worn that out). He looked very fresh, like he had gotten a normal amount of sleep. He sounded very chipper. Some of his comments (though I can remember anything exactly to quote) made it seem like his heart already belonged to one of the F2.
He also seemed very relieved that he came out of his segment unscathed ... considering he was backstage during the catfights with the F3 bachelorette and watched it on the monitor. He probably thought the high tension would translate to his segment.
