We are connected. We grew together, one baby split in two in a single womb. If I am different from them, then she is too. [And Helena so badly needs to feel different from what she's always been told the others were, a creature with a soul instead of an abomination, formed against God's will maybe, but with the potential to work her way back to the light, the potential to find her place in a lonely world.] I feel it. I felt it before I knew she was my sestra.

[Of course, Sarah was the first one she'd ever spoken to, ever seen up close. Twin connection aside, that may account for more than she realises herself.]
