Dr. Gretchen Kalbrenner

A native of West Germany, Gretchen Kalbrenner received a doctorate in molecular biology, becoming a renowned name in her field. Throughout her career, she has been known to be highly driven, motivated, and driven. However, some of her best colleagues would wish she'd take a little time to unwind now and then, with her hardworking demeanor leaving an impression of being cold and devoid of humor.

After receiving a grant, she began her current residency at Northwestern University in Chicago.

Kaitlyn Mitchell

Growing up in the Midwest, Kaitlyn always wanted to make something of herself, wanting early on to get into medicine. She had hopes of becoming a doctor, finding her path after her father lost one of his arms in an accident. She became obsessed with stem-cell research, determined to help her dad "grow back" his arm. After reading about Dr. Kalbrenner while writing one of her term papers in medical school, she began to idolize the doctor, feverishly applying to get into her biology program for her grad student studies.

The first few months of working together weren't easy. While Gretchen right away saw Kaitlyn's dedication and natural talents, she was a little less enthused about the girl's work ethic. Nevertheless, Kaitlyn sought out the good doctor's approval, constantly volunteering for lab work.

One night, putting in late hours in the lab, the two women began working with a top-secret experimental serum. It was designed to nearly rewrite molecular DNA as needed, with the hopes that if applied properly, it could construct lost or underdeveloped limbs, regrow damaged organs, and other wildly imagined things.

Gretchen once again warned Kaitlyn, in her stern German accent, to please be careful with the container. Kaitlyn, in her eagerness, had a mental lapse, temporarily dreaming of her dad having his lost arm regrown. It was only in that brief moment, as she punctured the serum lid with her syringe...

The explosion was bright and fast, spraying itself all over the two women. They fell over on their backs, blacking out as the backs of their heads hit the floor.

When they came to, the serum had worked all too well. It "assumed" that flesh from the two women were from the same body, and acted accordingly to "seal the wound". It left them as one body with two heads on one set of shoulders, two arms, two hearts, three lungs, two stomachs, one enlarged liver, one intestinal tract, eventually becoming one woman from the abdomen down.
