Bravo, MagnusTrask, for your comments about the joys of escapism!
Near the end of Leviathan, she and Quentin both commented that it had been a LONG TIME. Did that mean they both LIVED through the years? I have no idea.
Me neither, but it's an outstanding point. (I love that scene, btw, and I adore the spotted coat Angelique wore.) She also tells Quentin, "We're both a great deal older." The problem for me is that it still doesn't tell us if she lived through
all the years between 1897 and 1969 (as Quentin did), or just some of them; all we know for sure is that she disappeared toward the end of 1897. But would she have risked pursuing a modeling career-- a very public vocation, and possibly after having already given up her powers-- at the same time that her past self was torturing the local residents of Collinwood? Does DS canon even allow for that to happen? So even if Angelique remained on Earth beyond the 1897 storyline, she may still have eventually time skipped to a point in the present after Cassandra's destruction.
