Vincent's team examines his theory that FBI Special Agent Dana Landon's husband Sam Landon wasn't really JT's fellow prisoner but the fiend behind his open captor. Gabe's romantic trip plans with Cat are spoiled when Vincent must search his apartment and finds there the flaks with the 'beast cure' JT was forced to make, but the truth prevails. JT's Valentine Day's gifts for Tess prove a turnoff, but the solved cases quota demanded by her and Cat's new boss since Gabe returned to the DA, captain Ward, enables a welcome 'gesture'.
