Adelle says, "Pain reveals who you really are." The villain in Firefly (2002) episode 'War Stories' said something similar. Both series were created by Joss Whedon.
When Victor joins Scytheon, he's implanted with a chip that links his brainwave patterns with every soldier in their network. This allows him to share the senses of his comrades, making them a much more efficient fighting force that's able to truly move as "one." This concept was originally introduced in the 2008 KONAMI video game "Metal Gear Solid 4: Guns of the Patriots. In that storyline, a worldwide integrated Military Network called "Sons of the Patriots" linked all forms of information (including realtime biometrics) into their system. This allowed teams and battalions to operation literally as a single unit; sharing in each other's senses, reaction times and movements.
Ivy (Liza Lapira) wears a flamingo pin like Badger's (Mark Shepard) in Firefly. Both shows are created by Joss Whedon.
