The episode title is not presented onscreen until near the end of the episode.
Byakuya has strengthened his shikai to bankai level by relearning the basics of his blade.
Rukia's true power is decreasing her own body temp; her blade only extends her reach. She can temporarily kill herself in a sense and become immune to contaminated. Though As Nodt's feat power work on the nerves; which she needs to function while temporarily dead.
As Nodt's power works by stimulating the sense of self preservation in his victims. Because fear is the result of trying to stay alive.
