A/N: For those who are new to the Gemini AU - the brothers are meta-humans. Their power is fire elemental, but in its use they are fused into one person. That duality of personality in one body is why they call themselves "Gemini". Also the mental 'switch' that triggers them into Gemini, the first few days of empowerment, they chose as the snapping fingers of their left hands. Since both are right-handed, this would be unlikely to be accidentally triggered. Now, on to the story!

CHAPTER TWO

Feeling shaken by the eerie similarities of their families, the brothers decided to fly touched down on the Miller family's porch, and Dean stepped away from him, raising his hand to knock.

A woman's terrified scream aborted the knock, turning it into a kick that slammed the door open. Dean and Sam raced up the stairs, drawn by the sounds of male yelling.

A sudden loud – and very wet – noise erupted, followed by an eerie silence as they emerged into a hallway. The woman suddenly screamed again, and they spun to the right, racing down the hall and flinging open a door.

They saw a body – minus its head – sliding down to the floor beside a firmly closed window. It wore the same clothing Roger Miller had when they saw him earlier in the day.

The woman from the photograph – Alice Miller – was trying to press herself into the wall while a young man stood glaring at her, with a knife floating in mid-air between them. The man's head snapped to face them, and the knife fell to the ground. "Don't! Interfere!" he snarled.

Dean stepped in front of the woman. "Max, right? Max, come on – you really don't want to do this."

"Oh, yeah," he sneered. "I really do." The knife wobbled as it rose again. "Years of being beaten! Hated! By those two so-called 'pillars of the community' – while she did nothing! My only sin was my birth mother died in my room! Oh, no, you don't!" He spun to face Sam, who had been circling to grab him.

Sam gasped as he found himself airborne, propelled backward and into a small closet. He saw the door slam and heard something heavy roll in front of it.

Then he heard Max make a noise of satisfaction, and Dean make one of horror. Picking himself up, he ran his hands over the small of his back and groaned as he found his gun missing.

His vision was coming to vivid life. He tested the door and found it unmovable, so he took a small step backward in the tiny space.

Inside the small closet, and outside it, two left hands snapped simultaneously.

Alice and Max each cried out as Dean's form wavered. It grew slightly taller and the sandy hair lengthened and became fiery red. "Stay behind me," his altered voice ordered Alice.

Max's eyes were wild with insanity. They locked on the gun again, wavering it up between them. "What are you?" he screamed. "What the hell are you?"

A sad smile touched the altered face. "Like this – my name is Gemini."

"Not who – what are you?" Max growled.

"I'm what could have become you," Gemini said. "If my dad had blamed me. My mom died when I was six months – in a house fire. In my bedroom."

Max's jaw lowered.

Gemini nodded. "And I have psychic abilities, too. But like this?" He gestured at his body. "Fused like this, my brother and I have very different abilities."

"What... What are those?" Max asked, intrigued despite himself.

Gemini's hand flashed out. A jet of flame rocketed from it and struck the hovering gun, knocking it to the floor.

Max staggered, a hand flying to his forehead.

"Sorry in advance about the mess," Gemini said over his shoulder to Alice, before he raised his hand over his head.

A second, precisely aimed bolt of flame flared out and severed the cord holding up a light fixture. Before Max could even look up, it fell and took him to the ground with it.

Sam stepped away from Gemini and felt on Max's neck. "Alive – just out cold." He retrieved his gun as he stood up.

Dean turned and hugged Alice. "You're safe now," he soothed. "It's over."

"No!" Alice gasped, pushing him away. "Don't you see? He's his father's child! He won't stop – not till one of us is dead!" With that, she lunged for Sam's gun.

Sam caught her wrists. "Easy, settle down! Now, we're going to make sure he can't hurt you, okay? We'll find a way!"

Dean had his phone out and pressed against his ear. "Doctor Marilyn Evans, please," he said, naming the woman who had rapidly become their primary physician due to her knowing how to treat meta-humans, being one herself. "Hey, Doc – it's Dean. Listen, we've got a bit of an issue, though."

He listened to her for a second, then said, "No, neither of us. We're both fine. But we've got a psychotic telekinetic on our hands. Caperville, Michigan. Anyone nearby know how to dampen a psionic's powers?"
