Can we get a break down of the biological relationships between the various Fae Queens we have seen on screen? Of particular interest - Maeve and Sarissa, were they actually Mab's kids (biological sense)? If so, who was Mab's baby daddy?
Mab and Titania are actual twin sisters.
Maeve and Sarissa were twin sisters, from Mab. Their father was an Austrian composer and musician who died young.
I will break down the WOJ into two parts, from least complicated to most complicated with respect to my theory that Mab=Murphy, and then attempt to explain them.
Maeve and Sarissa were twin sisters, from Mab. Their father was an Austrian composer and musician who died young.
Note (Mab=Murphy) This requires Murphy to parent a set of twins with an Austrian composer and musician. She names them Maeve and Sarissa. She knows that Nemesis will likely get to Maeve, given her history on Demonreach in the future, her past, and for whatever reason (time travel paradox) still names them those same very names. She proceeds with plans to prevent this from occurring and despite all she does, it still happens.
Or, She knows her history, but the point in which she travels into the past she enters a slightly different alternate reality so she is uncertain as to exactly what will happen again.
Mab and Titania are actual twin sisters.
This one is the most problematic. I can explain it away a few different ways.
1) Biologically, over time, Mab and Titania become actual twin sisters. See the way the Lady mantle morph's Lily into looking like Aurora. Give it a few more decades, and they probably would look exactly alike.
2) Mab and Titania mantles are 'actual' twin sisters.
3) Murphy has a twin sister that accompanies her into the past to ascend the Queen mantles around the same time.
4) Murphy's evil/good twin, -Murphy, from an alternate reality travels into the past to ascend the Queen mantles around the same time. (she fits the definition of identical twin.) *Harry makes a joke about it in one of the books about Murphy having an evil twin. *We will likely see another Murphy in Mirror Mirror.
There is also this WOJ, that I have to navigate around.
I was wondering if Mab was the first Winter Queen?
No. Mab was not the first Mab. Mab was originally Winter Lady, and Lea was her Jenny Greenteeth. She was her sidekick and handmaiden. And so when Mab got promoted Lea did too. So she got to be much more powerful and awesome. But that was a while back. When that happened. And the same thing with Titania. The Winter Queens actually died. The last time things got awful in the wizard world. So things are about to get awful in the wizard world again and they're a bit nervous. They're a bit nervous about Dresden. Well, Titania is very nervous about Dresden. Mab is keeping her enemies close.
(*Mab=Murphy) This requires Murphy to be a Winter Lady, choose Lea to be her handmaiden. It seems "same thing" with Titania suggests our Titania (perhaps Murphy's twin) was Summer Lady. Both ascended in an event that took out the Mab and Titania of the time. And somehow both our Mab and Titania are skittish around Harry. With Mab, it's more about considering him an enemy. So, did Harry or something like Harry orchestrate, or directly take out, the prior Queens? They really have a hyperfocus on Harry personally, even before it seems Storm Front. It might have to do with what he was born to be.
