Cloudy with a Chance of Murder

The team investigates the death of a television weather forecaster who had discovered that a local manufacturer was using styrene in its carpet-making process and releasing chemicals, causing asthma in local children. Meanwhile, when asked on a date live on-air by entertainment reporter Kristina Coterra (Jodi Lyn O'Keefe), Castle accepts in order to maintain the pretense that he and Beckett are still unattached; this goes horribly awry when Kristina tries to seduce Castle at his loft.
