I know these aren't really accepted in the Fanfic community but JUST to clear up some confusion about Elizabeth, Stefan and Damon.
Elizabeth was born in 1862, which would make her 2 years old in 1864, when Stefan and Damon met Katherine.
Katherine killed Damon's wife, (my OC; Helena), and took Elizabeth when she was "burned in the church", after she turned Stefan and Damon.
Katherine waited until Elizabeth was 17 years old to turn her.
Elizabeth was turned 17 years after 1864, making the year she was turned 1881.
Which is why Stefan and Elizabeth are the same human age.
Stefan was 17 when Elizabeth was 2 years old, and he was turned when he was 17 years old.
Damon was 23 when he was turned, when Helena was killed by Katherine, and when Elizabeth was taken by Katherine.
That makes Stefan and Damon the same age in vampire years, but not in human years (obviously), and why it must have been confusing trying to figure out how everything worked out with their ages and numbers and what not! I hoped this cleared up some stuff, and I should be updating with an actual chapter next week, I am so so sorry I haven't updated. Stay tuned! ;)
