When Hiccup brought Viggo back to the base with a Skrill... you didn't question it. After years of friendship you'd learned that Hiccup always has a reason. And you trusted his judgement, so you let him lay Viggo down in your bed.

"He's in a bad state," you warned, carefully removing the arrows from Viggo's back. Hiccup sighed as he passed you the gauze.

"Can you do your best?"

You gave Hiccup an offended look. You may hate Viggo and everything he'd done, but you wouldn't let him die in your bed. The look was good enough for Hiccup and he raised his hands in surrender. The Skrill that had bonded to Viggo paced outside, peeking in through your open window. Your own dragon, a Deathsong named Rainbowspitter, nudged the dragon lightly.

Viggo was unconscious for three days. For three days you cared for his wounds that had begun slowly healing, while also making sure to care for the Skrill. However on the fourth day, you woke up in your makeshift bed to the sound of Viggo groaning softly.
