You had noticed Hiccup disappearing during the day, and he was extremely suspicious-looking while doing it.

He’d also gotten suspiciously good at handling the dragons during your training, though he refuses to harm the dragons. He somehow knows how to handle them with what looks like no problem.

So on this day, as the sun sets, you follow him. Hiccup picks up a few fish and begins his walk into the woods, where you follow from a safe distance.

And it ends… oddly. He enters an empty cove and dumps the fish in the sand. So that’s when you make your entrance.
