This is the relationship between the vampire Caroline Forbes and the Supernatural Hunter Jeremy Gilbert. They have not interacted much with each other, but have allied together almost constantly to stop outside forces from destroying Mystic Falls' legacy. They are currently no longer in contact being Jeremy moved away from Mystic Falls and Caroline moved to Dallas, Texas with Alaric Saltzman.
Caroline and Jeremy have presumably known each other their entire lives, as Jeremy's sister Elena is Caroline's best friend. They've had brief interactions throughout the course of the series to discuss what to do during the various supernatural emergencies the Mystic Falls Gang have experienced.
Throughout The Vampire Diaries Series
Caroline found out that he and Bonnie consummated their relationship and was thrilled for them, though she was slightly offended that she was not told sooner.
In Welcome to Paradise, Caroline was angry that her friends were ignoring the fact that everyone was still a mess from grief after Damon and Bonnie's deaths, and she took her anger out on Jeremy. She saw Jeremy with Sarah and lost her temper by making a rude comment about how he was trying to forget that Bonnie died by hooking up with random girls all summer. Later, Jeremy's deduction led both he and Caroline to realize that the anti-magic spell over Mystic Falls also removed vampire compulsion from any human who was compelled and then crossed over the border.
Although not seen interacting together, it can be assumed they are back in touch after the series finale. In I Was Feeling Epic, Caroline is seen reading a donation letter from Klaus Mikaelson which was supposed to support her new school for supernatural youngsters. Caroline looks to see Jeremy getting ready to teach with a bow and arrow in his hands. Caroline and Jeremy currently work at the Salvatore Boarding School together.
