Old Friends: A Ben Mason fanfic
Kat and Ben go way back. When the aliens attacked, they were harnessed together. Now Ben and Kat have been freed of the harness, but have not exactly gotten rid of all of the effects. They know they have a connection somehow, but with an alien war raging, there are more important things to do then fall in love. Soon these two will have to realize that no matter what they do, they can't change who they are, and what they feel.
