After some arboretum visits Dr. Crusher diagnoses nothing serious, but soon dozens of crew members get behavioral deviations, affecting appetite, memory and emotions. Reg Barclay takes care of Data's cat Spot, who is pregnant like nurse Alyssa Ogawa. Worf first fails testing or diagnosing his new guidance system, so Picard and Data chase a lost torpedo, then bites Deana and turns into an erratic beast due to a bite a sprays venom himself. By the time Picard and Data return, everyone aboard seems mutating and/or molested: the Enterprise has become a 'de-evolution zoo', Data believes by a virus reviving dormant genes from ancestral species. Picard is also infected, causing growing prey-anxiety. Nevertheless he must lure monstrous Worf away so Data can develop a retrovirus from genetic material after finding Spot's kittens remained perfectly feline when ma turned iguana. Written by
