Theory time!
So, the first time we see Dracula he finally rises from his deep sleep, only to discover he had missed 300 years.
In particular we get a shot of his right hand and we see that he's already wearing the Lycana ruby. Assuming he had worn it the moment he was put to sleep, this means that he had stolen it from the Upiri and had trapped them into his castle as bats before that.
This means that the Upiri had already stolen the ruby from Seymour and that he got stuck as a wolf around the time the clan wars took place. This means that he had already turned Ivy into a shadow before that.
Hence, both Ivy and Seymour are more than 300 years old.
But we know that the Heirs haven't seen the clan wars, and the way they speak about it is as if it's far history for them. Now this could mean that the Heirs are a decade or so years old or even a hundred years old each (I don't really know about this so I'm just speculating at this point).
But if that's so, Seymour should look much older than he does, unless being stuck as a wolf somehow slowed his aging process, and since Ivy is a shadow and we know that when shadows are hurt they revert back to how they looked the moment they were turned she could really be much older than she seems.
I don't know if this was obvious from the start or not but I was mindblown by this concept.
And nothing thank you for coming to my TEDtalk
hoo boy, if you only knew, I had an entire post about this in my drafts, I'm so happy other people noticed that as well!
