Full Name: Kristovo Martinez
Current Age: 30-31
Parents/Siblings: See "Double in Paradise"
Vocation: Undercover F.B.I. agent posing as a fix-it man
First Appearance in Abruptly Amy: "A New Beginning"
Memorable line: (smouldering) "Don't toy with me, Amy." ("A New Beginning")

Kristovo is Amy's partner in crime (stopping) and partner beneath the sheets.  He first entered the picture as the Barksdale's next door neighbor and town fix-it man, before Amy learned his true identity: that of an F.B.I. agent who moved to Rutherford to capture Amy's corrupt F.B.I. boss, Michael Fowler (aka "Chief").

From the pilot episode onward, Amy and Kristovo have been inseparable -- though only Amy would go so far as to call their relationship exclusive.  Kristovo has helped her with such hair-raising tasks as capturing the infamous Corona Coronada and bringing Andrea's mother to justice.  At the same time, we knew very little about Kristovo's background until "Double in Paradise."  In that episode, we learn that Kristovo's childhood in Cuba consisted of him growing up poor  in a broken family, and that he has no living blood relatives... until an assignment in Spain tells him otherwise.

Since the events in "Double in Paradise," some major fissures in Amy and Kristovo's relationship have appeared, ones that get partially healed in "A Very Amy Christmas."  But we wonder for how long...
