A bit dark.

The mad scientist could not help but laugh as his test subject stood in front of him, a shocked look on his face, hands on hips, dumbfounded at his new fate.

Hmmm, was 'his' the right term anymore? He chuckled a little at his own internal joke and marveled in his work.

It hadn't been easy, finding her and him. She had been the easier one, as there was some con in town and the number of people dressed up and cosplaying was high. Finding a woman with the right look for what he wanted to do was a rather easy affair.

No, what was more difficult was getting the right other subject for the test. He hadn't been as easy to find, and it took a full day of searching to find the right person, early twenties, fit, a stereotypical handsome guy.

He smiled as he thought about the procedure, how smooth it went, removing their heads and transplanting each onto the other's body. It went far smoother, he thought with a grin, than finding the right male subject for this little experiment, and now he could admire his work.

She had already left, cleverly managing to escape and rather than being angry, he was impressed by her intelligence and ingenuity, plus her bravery at what had to be a shocking turn of events. Now Subject Alpha, now he was a easier to keep contained. After all, you have to do more than stand there with a shocked look on your face to escape, don't you?
