You think this is showing off? No, Heeljitsu is designed to kill within the first strut! It's meant to put the slay in "Well, he's just doing dat walk on the runway." With no show and tell, it's meant to do what it says on the tin. Provide spice to the movements of style to align with the effectiveness of close quarter combat.
After learning the Heels dance routines, precipitants are meant to twirl and fight with their legs. The rest a dangerous puncturing instrument and the soul a meaty bludgeoning tool.
Jaime has outdone himself by learning the art.
