Stormy Night:

Astrid once-upon-a-time could've said she was afraid of nothing. Even the fear of the Flightmare had disappeared, and quite obviously the title "Astrid the Fearless" wasn't just dished out to everybody. No. You had to earn a title like that, and earn it she had.
But… ever since that lightning incident… everything had changed.
Granted, a lot of it had been a good change, like her and Hiccup being a "thing" now, and her finally figuring out how to train the Triple Stryke…
But a fear had been the big downful out of the entire event.
She could deal with her every so often stinging eyes or achey lids, she could handle that. But lightning? Not so much.
And it just so happened there was lightning tonight in the angry storm that wracked the night. With every 'crack' she'd let out a panicked cry before burrowing even further under the blankets, trying to block out the sounds that replayed over and over in her brain, ever plaguing her mind and body.
"Stop!" She screamed at the storm angrily. "You can't get me again!"
The door to her hut swung open, making Astrid gasp in shock and fear. The cold and damp wind ruffled her hair, forcing her to dive under the blankets again, childishly hoping if she hid the storm would leave.
"Astrid, what is it, what's wrong?" Hiccup's voice cried out. The sound of the howling wind dimmed, and Astrid no longer felt the cold breeze through the blanket. She peared out, instantly noticing Hiccup's worried expression. He was sitting on the edge of her bed, his hand resting on her shoulder lightly while his other was reaching towards her hesitantly.
She was about to look away and shrug him off, to tell him she was fine, by she caught his expression and noticed how his face was pale in the candlelight, and his brows were pinched together. He was soaking wet and shivering, causing her worry instincts to kick in.
"Hiccup-you're soaked." She murmured. "Why are you here?"
Hiccup looked towards the window, then looked back with an unreadable look, "Well… With the storm I figured you'd want some… Company..?"
Astrid smiled and pushed herself up, only to jump back under the blankets when more lightning cracked. She heard the scrape of medal against wood, along with fast paced and heavy breathing.
She looked out from the blanket, panicking when she saw Hiccup's shocked and pale face. He was shaking uncontrollably now, and Astrid knew it wasn't from the cold.
"Oh, gods, Hiccup- the storm…"
Astrid paused when she realized that now she and Hiccup shared the same fears. They both had had traumatic experiences with lightning, and both feared losing one another… How ironic.
And even though he too was afraid of the lightning even more so then her, he'd traveled through the storm just so he could be there for her.
Astrid wrapped her arms around Hiccup's torso before pulling him close, burying her face in his wet shirt as she tried to offer some comfort and warmth. Hiccup hugged her back fiercely, and the two sat for a long time in a tight embrace, neither loosening their hold.
Lighting thrashed again.
"St-stay with me?" Astrid whispered.
Hiccup nodded mutely before sitting beside her, his arms still wrapped about her small frame- almost protectively. Yet she knew he was drawing as much comfort out of the embrace as he was giving it, and for that she was grateful.
More lightning, but this time Astrid found she could ignore it, now that she had Hiccup by her side. She knew that if he was near, she was safe. That Hiccup wouldn't let anything ever happen to her.
And she was determined to return the favor.
She hugged him harder, that promise playing over in her mind as she drifted off to sleep.

I know it's not very good, but when I'm on my kindle I tend to write lowsier… sorry. XD
