Cali , that's the first thing I thought (about the clock) when Ken or Gerard starting saying "Okay, 1+2 is 3....". It's totally easy when you add backwards.
The alliance swapping is dumb. I have a feeling Derek is skeptical about the whole thing.... Afterall, he DID tell Flo she was the dirtiest player in the game and he knew he couldn't trust them. I think the twins seem to be holding a grudge against the brothers because they didn't take the same direction last week when heading to Fussen.
The CBS teaser for next week says something about one team getting into a disagreement about aligning with another team. So perhaps Drew and Derek have differing opinions on this alliance thing. Personally I think they should stick with their gut instinct on this one.
