Determination

The lesson that a determined Hiccup is an essentially unstoppable Hiccup is, embarrassingly enough, one the people of Berk learned the hard way.

Hiccup is the kind of person who, once he sets his mind to do something, will do it, and so help anyone who gets in his way.

They have seen it so many times, and will undoubtedly see it many times more. Many. Times. More.

So Many.

Once they got used to it, however, it became entirely too hilarious to watch outsiders meet Hiccup, do something to bring out such determination, get in his way, and be very shocked and surprised when he ran roughshod over absolutely everything.

The chaos was always utterly GLORIOUS, and the expressions of the outsiders always priceless.

The other Viking tribes were, needless to say, wary whenever they came to Berk.

Not they were wrong to be so.
