Headcanon where Jack always brings back food from his travels for Hiccup.They eat them with milk snuggled under a blanket, Hiccup relishing in the moment because he never had something so sweet or tasty in Berk.
Jack doesn’t really need to eat so he won’t touch his and give it to Hiccup afterwards, because just seeing his satisfied face while eating makes all the wanderings around the world worth it.

You know why you have this.
