my prediction for the future episodes

Hope will help with CJ rehab. in turn since Hope operation might or might not have worked (there is a reason why I said might or might not have worked. can you guess why?) . CJ teaches Hope to fight blind with the Katana.
Mr Fix-it Datu will craft a prosthetic leg for CJ that is just as good as her own.With a built sheath for a slightly modified Wakizashi or Tanto. (just in case some of you don't know that the Wakizashi is a short sward to the Katana and the Tanto is more like a knife.)

Kelly and Victor will get it on hot and heavy.
Riley will go hunting for Scratch after viewing the video of Scratch killing Angel. She will disappear and never to be seen or heard from again after putting a final arrow in Scratch's head (she uses almost a whole quiver of arrows pinning Scratch to the wall.

what you think KC?
