The "Big Sister"
"The Children of St. Lutgardis Orphanage claim that a 'skinny monster' with a single red glowing eye invaded their quarters and abducted six-year-old Chantal Dumas.
"Little is known of the kidnapper except that the individual may be unusually thin, over two meters in height, and should be considered armed and dangerous." - Newspaper cutting
Most witness descriptions point to one of Rapture's iconic Big Daddies as the mysterious assailant behind the kidnappings... but it's clear this is not the kind of Daddy we remember.
The "Big Sister", as it's being dubbed, is described as "skinny", over 2 metres tall with dexterity and "incredible speed". We also know that it's intelligent; one newspaper report in Felixstowe, UK describes a window entry of "extreme precision", with little evidence of entry left behind. All sightings describe a single red light attached to the assailants head.
The first update on Something in the Sea shows a hand-made child's toy "of most singular design" discovered on a nearby beach, said to resemble the peculiar being.
There was also a discovery of strange, small footprints on the neighbouring sand alongside the item. "The metallic soles do not resemble any civilian or military footgear," claims the man on the scene, pointing out the assailant's "unusually long stride."
So what exactly is a "Big Sister"? So far there's no official answer but one possibility lies with the fate of Bridgette Tenenbaum, the genetic scientist who created Adam and helped you free the Little Sisters from Rapture. Tenenbaum's fate is unclear at the end of the first BioShock, but it's likely she was left behind as the only intelligent being alone in the city.
Now this is going out on a limb, but we reckon if we were left alone in an underwater dystopia, full of crazy murderers and mutants for seven years... we'd go a bit mental. And it's possible that Tenenbaum has too. In her insanity has the good doctor suited up and gone on a quest to snatch back her children? That's where our money is, anyway.
