I've been told I need to balance out my fluff and angst combinations. How's this?

Thunderstorms

Oliver hated thunderstorms. They brought back memories of the night The Queen's Gambit sank, as well as the island. Every clap of thunder was a fired bullet heading for Yao Fei or Shado, even his father; a missile being launched, or the sound a torpedo made as it collided with a metal freighter.

Arrows didn't do that. Except for a whoosh of air or the snap of a bowstring, they were silent. Sometimes he wondered if that was the reason he used them, rather than as a tribute to lost friends.

Felicity didn't care much for thunderstorms either. They reminded her of sitting in an old factory basement, praying the ceiling wouldn't cave in on her. She also didn't like how thunder and lightning just came out of nowhere; it always scared the crap out of her.

Which was why when Oliver came out of the bedroom, she was sitting on the couch cradling a cup of tea and definitely not staring at his abs.

"What are you doing up?" Oliver asked, his voice raspy with sleep. "I've never been able to sleep during thunderstorms," she answered, her knees drawn up to her chest. She probably looked ridiculous, curled up in her pajamas like an armadillo with a bedhead.

"I used to be able to," Oliver said. The unspoken "Before the island" hung in the air between them.

"I could, but…" Felicity trailed off. She wasn't sure she wanted to tell this story, but Oliver had told her everything that had happened on the island. Why shouldn't she tell a secret for once?

"The night my dad took off, there was a really bad storm. Mom let me stay up all night on the couch, so I waited for him to come back, but...he never did." Felicity dropped her gaze to the tea in her cup.

"I'm sorry," Oliver said quietly. Felicity tried to shrug noncommittally. "When I got older, I tried finding him, but Damien Jacob Smoak had dropped off the face of the earth. Usually, I can find anybody, but when it comes to my own father-"

Her voice cracked, and she shook her head. "Sorry, I'm rambling again."

Oliver sat down next to her on the couch, and wrapped his arms around her shoulders, pulling her to him. "It's fine," he said softly. Felicity blinked back tears and tried to focus on his warmth. Lightning flashed, and a crack of thunder rattled the windows, causing Felicity to squeak and screw her eyes shut. Oliver's fingers combed through her hair. "It's okay. You're alright," he whispered.

For a while, they sat there, just listening to the other's breathing and heartbeat.

"Felicity," Oliver said suddenly.

"Yeah?"

"I'm never leaving you," he said gently. "You know that, right?"

She swallowed hard. "Right," she whispered.

They may have issues, but they are adorable.
