When Derek is coerced by his girlfriend Savannah to go with her to a Latino dance club, he is in for a surprise: among the dancers there, he discovers Spencer. But Spencer denies ever having been to the club the next morning. Derek can't get the paradox out of his head: on the one hand, he has experienced Spencer as a sexy dancer with a fiery Latina, but on the other hand, his friend and colleague on the case they are currently working on once again proves to be absolutely helpless when it comes to communicating with women. How does this fit together? Derek decides to get to the bottom of it.
