19. The Bride Reads Her Own Palms
This one might seem obvious but it's easily missed if you're not paying total attention.
After the Bride wakes up distraught, she comments that she's been unconscious for four years, despite seemingly having no visual frame of reference to immediately know this.
Yet the Bride is staring at her hands when she says this, and Tarantino even provides an extreme close-up of her palm lines to hammer the point home: the Bride is using palmistry to read her palms and deduce how much time has passed.
Some fans have even theorised that she could've learned this from the Pai Mei (Gordon Liu), who in Volume 2 we learn also taught her the Five Point Palm Exploding Heart Technique.
