Dax reaches Deck 12, but is a few corridors away from Environmental Control System when he hears the bulkhead stretching and expanding. As he approaches the doorway to Environmental Controls, he hears the giggling girl echoing throughout the corridors.
"Come Play with Me!!" says the voice. Dax turns his head behind him to see the dark figure with the gleeful smile about a few feet away from him and its coming closer. As it approaches him with it's smile shifting from side to side with each stride it takes. Dax's first initial thought is to run like hell, so he does, he begins to enter Environmental Controls Room, but is stopped by a plasma fire that has enveloped the entire room, he can't do anything about plasma fire, since oxygen itself is feeding it. So he heads out of there and heads towards the nearest jefferies tube.
Giggling the dark figure goes, "No No No. Not that way you don't!" An explosion from the bulkhead near the jefferies tube door, and it throws Dax back. As he lays on his back, he opens one eye partial to attempt to gather what strength he has to get out of there, but he begins to feel cold. He tilts his head to see a piece of metal has plunged into the side of his abdomen. "Well that explains it." And before he knew it, the dark figure was looming over him.
"Hehehehehehehehe. Let's play a game." And Dax passes out.
