Back in time

In the start bonnie took Caroline back in time to kill the Mikaelson's but instead of that plan Caroline falls in love with the human Niklaus Mikaelson who back in the future is a total jerk and is a beast and to his father an abomination and Caroline tells (human) klaus what will happen to his little brother so he knew not to go to see the wolf packs turn to there wolf form but Ester ends up having her eighth child and she ends up dead on the night that klaus and Henric were gonna see the wolf pack Ester still turns all of her children into the first of the vampire species but before that happens klaus proposes to Caroline and turns her into a hybrid instead of an original but she is an original hybrid just like klaus, what if when she finds away back home she tells them not to change anything else what happens when she sees her "Family" again and what happens when before she left back to the future she becomes pregnant and the baby is still in her what happens when care sees Nik again
