Hiccuping

Rachel was on Hiccup's team when he defeated the Red Death, and the dragons began living on Otter. Rachel had a Skrill dragon, lightning-fast, black and purple, similar to Toothless's level; no one could tame it. The team also included Fishy on Grimel, Snotlout on Horrible Beast, Astrid on Nadder, Tuffnut and Bully on Prestige, and Hiccup on Toothless.
Today, a girl named Header came to Otter. Rachel didn't believe her, but Hiccup did. They invited Header to Otter. Header slept with Hiccup. In fact, Header was a liar; she was sent by the Outcasts, the enemies of Otter, to get the Book of Dragons. So Rachel stood there and argued with Hiccup because he didn't believe her, saying that Header was lying and pretending to be someone she wasn't.
