You want to call it a show of strength or "see who is the strongest for the woman we want"... but in the end Hans and Kristoff met in the great room to challenge each other, almost completely naked. It goes without saying that the mountain man, so used to carrying wood, chopping it with pure male strength, has dominated that pussy that is the little soldier prince. That's why when he realizes he has the upper hand right away, he decides to continue humiliating him with his barbaric and fighting skills.
If u wanna see a last domination moment, put a Heart under this post and I will make u happy >:)
