Dick seems to deal with him as if they have no history at all outside of Jason being a minor villain Dick didn't have much to do with ever
But that's the point, whilst Dick and circus-Jason were pretty close, Dick and angry-Jason had almost ZERO interaction prior to Jason's death.
The intro of angry-Jason came after a complete estrangement between Dick and Bruce, when Bruce fired him from the role of Robin, and Dick was working full time with the Titans by then. They worked together something like twice, once when Dick came to investigate rumours of the new Robin then in the Brother Blood denoument, during most of which time Dick was being mind controlled and fighting against Jason. (Make it three times if you count the retconned in meeting in Nightwing: Year 1)
There was little frsaternal feeling between them, though the last time they met in the Titans, Dick did thank him for coming to help rescue him from Blood.
