This article lists the interactions between Knife and Suitcase.
Knife and Suitcase were both on the Grand Slams, but only had select interactions throughout most of season 2. They did not have a strongly defined relationship until Truth or Flare. In it, they voiced their mutual respect and support of each other that had only been briefly shown before then, at best. Despite being very different and competing against each other in the finale, Knife and Suitcase seem to generally be on good terms.
