The Hermit (9)

"A Little Sister? Where's the Big Daddy?"
"I don't know, but you keep a lookout for-"
"And let you get all the ADAM? No way."
"Ugh, fine. We'd better get her before the Daddy gets here."
The two splicers advanced upon the little girl. The little girl was clad in a girlish and dollish dress, with a bow upon her head. She carried her needle almost as tall as her on her right arm. Her eyes had no irises, no pupils, just two large round bright yellow orbs.
She whimpered, "Don't hurt me!"
"Now now, we all know what you are, Sister. Your ADAM is ours."
The Sister cried out, "Mr Bubbles!"
And with a furious roar, a Big Daddy charged out at the splicers with a speed which belied his lumbering size. As it charged, you could hear a deep moan, much like whales and its drill spinning up.
"Bloody 'ell! I told you to watch out for him!" The first splicer shouted as he attempted to evade the monstrous steel-bound figure.
The second splicer wasn't so lucky. He was slammed against a wall by the Daddy and was drilled through in an incredibly messy fashion. The splicer screamed in agony as his entire body was ripped to bits.
The surviving splicer took out his gun and started to shoot at the Daddy, but his bullets had no effect as it bounced off his armoured diving suit.
"Shit, shit, shit!" The splicer had a tone of desperation.
With another low groan, the Big Daddy revved up his drill again and charged the splicer.
The splicer followed the same fate as his companion.
"Thank you, Mr B. They've turned into angels now." The Little Sister smiled a beatific, angelic and horrifically innocent smile and walked over to the corpses, the Big Daddy followed in tow. A passer-by might actually believe from her smile that nothing had happened and this made it all the more disturbing, like she did believe that nothing wrong had occured.
The Little Sister started stabbing her needle into the dead splicers and extracted a red liquid that was unlike blood and seemed much brighter.

In Rapture, the hunters get hunted if they're not careful. Isolation to an underwater city does terrible things.
