So, I've been thinking again (Dagur, you think too much) about how old Heather, Dagur, and Oswald might be. I have looked at all three pages and not one of them have an age. This is going to be a long post, but it will NOT be spam. And please comment good ideas.
So, first, in RoB, Hiccup is 16. Heather is about a year or two younger then Hiccup. Which makes Heather 14-15. In RttE, Hiccup is 19, which makes Heather 16-17. Let's say she is 17, because it sounds just about right.
In RoB and DoB, Hiccup is 16. Dagur is about 3-4 years older then Hiccup. Which makes Dagur 19-20. In RttE, Dagur spent three years in prison. Also in RttE, Hiccup is 19. Which makes Dagur 22-23. To round it off, let's just say hes 23.
If Dagur is 23, and Heather is 17, there is a 6 year difference between the two. As for Oswald, it's a little crazy.
Because Dagur and Hiccup are the two youngest chiefs, that means Oswald couldn't be under 20 when he became chief. So, let's say he was 30 when he became chief. Then, in a comic book (which I have not read, but have herd of), it was said that Oswald attacked Berk. So let's say before it starts, during, and after the attack, it took 5 years. Then Oswald held peace for 50 years.
So far, we are at 85 for Oswald's age. Then he dissapered, Dagur became chief, Dagur went to prison, and everything went crazy. That would be another 5 years. Now, Oswald could be 90. But he died. Let's leave it at that.
So, if Dagur is 23, that means Oswald was 67 when Dagur was born. If Heather is 17, that means Oswald was 73 when Heather was born. Why so old?
The real question I will ask later, because this post is really long. But, this post should give you a hint at the "real question". Keep looking for the "real question" in the "Discuss" page. I will post it as soon as I get comments on this one.
