The burning questions I have are: how is Davina so powerful? They say she's more than just a witch, she's something more supernatural, what does that mean? Did Marcel raise her or something? Did Marcel just discover this girl or steal her from her parents?
I wonder if marcel had any kids or relatives from when he was human, apart from his father? It would be a simple expalnation if she was actually related to him.
THe only time a witch has matched an original is when bonnie was using expression, she help kol and klaus at bay, then bound him in a room. SO expression is a possibility, we know there was once a sacrifice of 12 in the city, it might have been expaned into a triangle. THe thing is, expression witches seem to melt down, the only one that we are not sure about is quetsia, and she was not exactly stable.
THere is one other time, was when bonnie was using the power of a hundred dead witches, or esther was using the power of the whole bennet line. Since the witches of the city draw their power from their ancestors, if one of them could draw upon enough of them at once, then they would easily have the power. How many witches have been born, lived and died in this city, for their power to have accumilated, 1000 , 10000 or even more. I am reminded of the silas tombstone, bonnie was able to link it to evey sacrifice of the expression triangle, so say a similar talisman was linked to the witches cemetary's, then that item would have a direct link to the source of the witches power.
With regards to her powers, as I understand it she inherited the powers from the three dead witches of the sacrifice - it seemed to pass from one to the next as each girl died and since Davina was last in line, she got all their powers.
As for parentage I suppose her parents gave up on her. My memory of the episode is shaky but I had the impression that when Davina looked for support her parents turned away from her, which was when Marcel leaped in and brought her away. After that, I guess he took on the role as guardian. He related to her and I think he told Klaus he disapproved of killing children, so I guess in any case it wouldn't have mattered if her parents told someone about their daughter's disappearance - the city is dominated by vampires and her disappearing was sketchy. I'm guessing he didn't raise her for most of her life - just from the Harvest up until now.
Marcel's family, I think, was sparse: according to his page on here he had a half-brother, whom we saw Klaus kill because the guy breathed near Klaus. No, sorry, he was in love with Rebekah and wanted to be turned, and he said something Klaus didn't like, so Klaus killed him. Presumably he died before he had kids, and it seems to me that the brother and parents were Marcels' only family. If Marcel turned before he had kids, which I think he did, then I don't think he had any family other than the Originals.
What do you think?
