I'd have to say his CR with Gorthan and Agnus. I say both of them because they're working together on a project. I just find it fascinating how well they manage to work despite being perpetual loners outside of Route. Of course, it's no secret that Dist grates on them as he usually does to anyone, but the fact that they put up with him is a miracle.

Gorthan and Dist's CR in particular is really interesting to me, because in their very first meeting Gorthan pushed Dist out of every boundary he had put up around himself. Gorthan sympathized with Dist. Naturally Dist didn't react well to it and he often argues with Gorthan about their differing viewpoints, but there was a seed planted that first meeting. Dist has this feeling that he can talk to Gorthan about things that he originally wanted to keep to himself forever, but how long it'll take for him to actually admit to his faults and do so is unknown.
