Tatia was innocent and pure and when she smiled, Elijah couldn't help but smile back; she made his life brighter by being alive and some nights, he would hold her close and stroke her hair while she breathed his name in her sleep.
Klaus loved the passion Tatia hid so well from the public eye and the seductive way she looked at him when no one was looking often made him fantasize about pushing her up against a tree and taking what her eyes so clearly conveyed she wanted; and on those nights she'd come to him he'd do exactly that until she'd scream his name.
Tatia had never been very decisive—her momma used to tell her so all the time back when she was younger—so when they ask her to do so, she looks at them both in turn and said, "Why should I have to choose?" her eyes going all innocent with Elijah and lust-filled with Klaus; and that night she didn't choose and it was brilliant.
