Lil more on Leah.. and Bob. her dual personalities manifesting reminds me of Bob, who's personality is split based on if he's powered by magic or unmagic. His shadow, though split from himself has continued to manifest as part of reality. Until their recent battle where I think I know what happened to him based on a theory about GK's soul acting as a prison for evil and DR using goodness to contain evil.
Bob first split himself which I'd parallel to Summer and Winter Queen's splitting. In their battle he subdued him with a prison inside himself I think. Evil Bob was captured by Bob after Bob severed the original connection, but the Shadow/mirror between the two still existed.
*Sigh* I've considered the nominal possibility.. she(Molly) dealt with similar things as Maggie as a child but didn't always fair so well.. cheering myself at the thought of little champions of good following dresden around during GP. "For the unborn!"
