Enjoyed the dance fight at the end
I liked the choreography of when Adelaide is fighting Clone Red. It was pretty cool and then finished by slamming those scissors deep inside, owies.
shareHow was a human more agile and strong than a clone?
sharethey grew up differently
shareThe tethered appear to be just as strong as the above-ground people, maybe even stronger. They're just more savage.
The "dance fight" reflects this; Red moves quickly and gracefully while Adelaide (who is of course already wounded and shackled) attacks with force and brutality (as she did earlier in their friends' house).
It all foreshadows the reveal that Adelaide is actually the tethered, and Red is actually the original Adelaide.
