The Scar is the title of a Lost Files Pre-order exclusive chapter of The Fall of Five. It is narrated by Number Six shortly after she is punched in the head by Five's metal fist and then healed by Marina.
Number Six, Nine, Eight, Marina and Five have traveled to the Everglades in order to find Five's chest, they come across a three headed alligator and battle it. Before being struck by Five, Six remembers striking the beast with lightning, Five blowing into his obsidian flute and bickering with Nine.
As she slowly awakens from unconsciousness, after her skull is fractured by Five's punch, she feels Marina healing her but she is immobilized by the pain. She remembers renting the fan propelled boat, travelling though the everglades and battling with the three headed alligator but is unable to recall how she was taken down.
While gathering her strength, Six attempts to work out what is happening around her, she hears fighting and shouting but she is unsure who is involved. She opens her eyes to see Eight pleading for calm and Nine badly injured.
Six finally manages to stand and sees a shape moving in the sky, hears more shouting and then is knocked back down as a scar sears itself into her ankle.
