* [=LaCroix=] and his daughter survived the eruption of Mount Vesuvius how? Yeah they might have survived the rubble, but even vampires in the show are vulnerable to fire and a pyroclastic flow is how much hotter than normal fire?
** They could potentially have taken to the air in time to escape the worst of it, if they saw it coming far enough ahead of time....vampire top speed was never determined on-screen.
*** They were in a building which was buried, rather than directly hit by it.
