Hiccup is a teammate and therefore an AWESOME DUDE. He also hits a lot of her must protect!!1!1! pings by ... being himself. She wants to get to know him better and there is plenty of time to do that because they're on the same team. It is a very positive relationship though and positive relationships are always good.

Also stop hiding things Hiccup. Does Marine need to get extra pushy and nosy on him? Because she will.

Also reverse me. '^'
