I gathered up one of my robes and some bandages and raced out of Lynn's carriage. With a bit of self-generated illumination it was simple enough to follow the bloody footprints of my doppleganger beneath the desert stars. I found her collapsed in an alleyway between the shacks of two merchants that had shuttered their gates for the evening.
She was still breathing. She groaned in protest as I turned her on her side. As I suspected, she was bleeding out from the apertures in the small of her back meant for my engine. The same precaution Dr. Mason designed to keep me alive was now imperiling the life of...me? I addressed her in hopes she retained at least some of my faculties.
"Qlippothic. I am going to tesseract with you to Dr. Mason. He needs to install..."
"I NEED NO ONE!"
The deafening crack of an Eldritch Bolt sent me sprawling. My senses reeled as I struggled to regain control of my neural net. My double crawled over me, her eyes wide and her grin twisted in madness.
"Oh how rude of me! I'm terribly sorry. I appreciate that you've taken good care of my body while I was gone, but..." She glanced up at the crescent moon, then leaned down again to whisper where my ear would be. "This form is a bit inconvenient for my plans."
She rose, taking my folded clothes from where they fell as she did so.
"You brought me a pink loincloth?" I heard muttering incantations as she fumbled with the garments. By the time I saw my attacker's face again, the voice had dropped a register. What were my features and brown hair had turned to coarser features and a 5 o'clock shadow. A strong resemblance to Dr. Mason, but thinner and without the mustache. I heard Lynn calling out my name a few blocks away.
"If you value your friend's life, you will tell no one you saw me." He stepped on my faceplate with his bare foot as he departed. "Now go save your fellow tinkertoy. And don't forget...Uncle Marcus is watching you!"
His vicious laughter echoed in my memories as Lynn helped me to my feet.
"Did you find her?" She asked.
I shook my head. "She...did not last. She is gone."
