Evil Twin Challenge
Twin sisters wake up in a strange and seemingly never ending cruise ship. Masks of rabbits that refuse to be removed attached to their faces. A disembodied voice tells them that they are to try to survive for their place on the ark. There are many other people in all sorts of animal masks. Some trying to escape, some try to survive, but too many trust the voice and snap.
and her twin
The voice tells the twins one last thing before it goes silent, their names won't work here, but that they should be careful about using their new names too much. They wandered for what could have been days, hunger, thirst and sleep all become distant in urgency.
Till they were eventually ambushed by a young man and young woman wearing dog masks, having driven Lucky and Bad into a dead end. After Lucky fails to reason with the couple Bad decides to fight back and kills the man with what appears to be unusual speed and strength. The woman enraged charges with a knife at Bad while she is in the midst of gloating over her kill. Before the woman's knife can find it's way into Bad, Lucky drives in front of the blade, shielding her sister. Lucky takes several slashes to the face and neck, apparently by passing the mask. It only takes a second for Bad to realises what her sister has done and throws Lucky out of the way and grab the woman in the dog masks wrist and braking it. The woman immobilised by the pain falls to her knees allowing Bad to carry Lucky away to safety.
Bad tended to her sister's wounds for days while hiding in one of the many cabins on the ship. Once Bad was sure Lucky would recover, she leaves her sister all alone without saying goodbye. She doesn't want her sister to discover what she's been thinking and what she's been feeling since she killed the man in the dog mask.
