fun fact bc i don't know how to sneak this into the story: 23 doesn't get periods because her healing factor doesn't really allow her uterine lining to shed. it is also in my head that she, or really any super healing characters, can't get pregnant because her body would recognize the fetus as a parasite (bc that's how they act in the body during pregnancy) and would terminate it naturally before she'd even have a chance to know she *was* pregnant
