Headcanon aph Iceland's scared of the dark
when he was little, iceland would nervously come into den and nor’s bedroom in the middle of the night, saying that there was a scary monster in the closet
so then denmark would take out his axe and make a big show of proving that no monster could possibly hurt him! denmark is a mighty viking who will fight them all off!
and then norway tells iceland that the only monsters and strange creatures in the house are his friends, and that they are here to protect him, guarding him from anything that would want to hurt him
and then they let little icey sleep in their bed for the night, just to make sure that he feels safe and happy, cuddled between his brothers
