A/N: So this is the start of my second story with my OC, Samanthea Winchester. For those of the Star Trek world who don't know the TV show 'Supernatural' all that well, my Sam is a descendant of one of the brothers from the show. All is explained within the story (I don't think I've missed anything), and I hope you enjoy it.

A/N2: For those of the 'Supernatural' world who haven't read my story, Not Alone, Sam is half Vulcan. Her father saved her mother from something (I haven't explained what in that story), but was injured badly enough that she took care of him. They fell in love only for T'Hea to die during childbirth many years later. Sam's father left Vulcan and she was raised as a Hunter, while keeping her existence secret. If you want to know more, feel free to read Not Alone. It's not essential, but may explain a few things.

A/N3: This chapter is the same as the last chapter of Not Alone, with a few words altered for those who do not know the Start Trek universe.

Disclaimer: I don't own the Star Trek characters nor the Supernatural ones.

Captain James 'Jim' T. Kirk, captain of the USS Enterprise, looked around as the lights in the mess hall suddenly flickered and the temperature dropped enough that he could see his breath for a moment. He breathed out again, and a fog formed in front of his mouth. He looked around to Commander Spock as the silence registered. The lights never flickered unless there was major damage, and the cold only happened when there was a hull breach. Everyone was still and had remained in their seats.

Except for his half Vulcan Navigator, Samanthea Winchester. She had stood, stepping clear of the table and pulling on her gloves. She then picked up a salt shaker, broke it open and held it in her hand. She was looking around the room, her eyes never resting on anything for more than a few seconds. Jim saw another person standing, and Winchester's roaming eyes latched onto them. It was Ensign Sable, a Thesian that had joined them after their stopover at Earth. It, (no one knew if it was male or female, and Sable hadn't said) had started to advance on a young female Lt, Tig'san.

"Hey!" Winchester called out suddenly, making the Ensgin turn to her. "Leave him."

Jim wondered what she was talking about, until the Ensign spoke. Jim had spoken to Sable a couple of times, and he sounded nothing like she did then.

"Why, when he has so many arms to use?" The Thesian had four arms, and Scotty had found them very useful over the past several months since he had joined engineering.

Well, that answered the gender question. He thought. But what the hell was going on?

Winchester suddenly held out her hand, "Spock, don't!"

Spock was still standing beside him, not behind Sable, as her hand was indicating. But it had the desired effect, making Sable turn around. Then, with the speed at which only a Vulcan can move, she raced over to him and shoved a fist full of salt into his mouth.

Jim watched in shock as something exploded out the back of the Ensign. It vanished so fast all he could see of it was a grey-black blur.

"It's ok, you're ok now, it's gone, you're safe." He heard Winchester murmur over and over again as she laid Sable on the floor, Dr Leonard 'Bones' McCoy wiping his face as he rushed over to help the man. Jim was shocked to see black goo running from his mouth, eyes, nose and ears. He looked to Spock, but he looked as shocked as he did, as did everyone else in the room. He went over and was about to demand an answer when a sound came from her. She reached behind her and pulled something from her back pocket.

She took a moment to look at the screen before flipping it open and answering, placing it so it covered the side of her face from her ear to her mouth. It looked like a communicator, but not. "What have you got, Dean?" She reached out to the Ensign's face as she listened, "Because I'm older, and I asked first." She growled as she wiped some of the goo onto her glove-covered fingertips. She suddenly winced at the reply, before sighing deeply.

She took a breath as she rubbed her fingers and thumb together, smearing the black substance. "Ectoplasm, I've got ectoplasm." She stood and looked at him then, "We've got one seriously pissed off spirit on board."
