Summary: Oliver investigates a lead on Walter's whereabouts but things don't turn out as planned.

Felicity sat in the dark of the foundry with only the soft glow of her computer screens providing enough light for her to work. Eyes never leaving the monitor before her, she adjusted her glasses and continued clacking away on the keyboard, bringing up different views from the many security cameras placed in the abandoned building that Oliver was currently searching.

Finally, she found his location on a camera in the north wing of the building. She brought the full-sized image up onto her computer screen and watched as he slid through the shadows effortlessly, like the darkness was an extension of his own body. The man never ceased to amaze her. And annoy her. And stress her out.

Right now, she was all stress. Her stomach felt off, like her gut was telling her that something bad was going to happen tonight.

"I don't like this, Oliver." She finally voiced her opinion aloud by whispering into the microphone of her headset.

On screen, she saw him still in response to her words.

"Why, what's wrong?" His voice came back low and gravelly in her ear.

"If Walter is really in this building, then where's all the security?" Felicity questioned aloud, more to herself than to Oliver, "He's a billionaire and a respected public figure. Everyone is looking for him. Wouldn't you expect his captors to take major precautions to keep his whereabouts a secret?"

"You don't think he's here?" was Oliver's calm reply, "All the signs pointed to this location."

"This place is too quiet. It doesn't feel right." Felicity frowned and shifted in her chair, still unable to shake her uneasiness.

"Let me finish this floor and then I'll head back to the cave, ok?"

She smiled a little at his reply. Lately she had taken to calling their little lair the "Arrow Cave" and Oliver had finally relented, occasionally referring to it as that as well.

"Ok," Felicity responded, doing another quick scan of her screens, "you're all clear up ahead. When you reach the end of the hall, take the door on your left. It's a stairwell that will get you to the ground floor, then back outside."

"Thanks, Felicity." His voice softened with gratitude and she saw him continue down the hall stealthily.

Still feeling a nagging doubt in her stomach, Felicity decided to scan some additional information on the building. It was the former headquarters of a company that had gone under after the CEO was convicted of embezzlement. The property had never sold after that, with businessmen too superstitious to start their companies with a history like that hanging over their heads. Now it was run-down and decrepit, located in the outskirts of the city with no surrounding structures. The perfect place to keep the victim of a kidnapping.

Felicity's fuchsia pink lips pressed together in thought. Her instincts were never wrong, and right now they were telling her that Oliver was in serious trouble.

She began to pull up blueprints and 3D reconstructions of the building, looking for anything out of the ordinary. Finding nothing, she decided to switch the security camera footage from the eerie green glow of night vision to thermographic imaging instead.

Scanning her screens, she saw Oliver's body in bright reds and yellows. Scientific proof that he had a hot body, Felicity thought with a grin.

Suddenly something caught her eye. In the room next to where Oliver was standing, she saw a pink glow. Not large enough or hot enough to be a human, and she knew from her research that the building's electricity had been cut years ago. There was absolutely no reason for something to be giving off heat inside that office.

Her stomach pooled with dread as Felicity gripped her microphone, "Oliver, get out of there right now." She spoke firmly, trying not to let her voice wobble with fear.

"Fel-"

"It's a trap. There's an explosive in the next room. Oliver, get out NOW!" She shrieked into her headset.

Her heart was pounding and the image on her monitor started to swim in front of her eyes. She vaguely registered seeing Oliver burst through the door that lead to the stairs, then there was fire. A great, loud explosion that she heard through her headset and saw erupting on screen.

Trying desperately to regain some of her composure, Felicity fumbled for her cell phone and was just about to hit 'speed dial 2' for Diggle when she heard Oliver's voice in her ear.

"Felicity, you there?"

"Y-yeah. Yes." She answered more steadily, "Are you ok?"

"Fine." She heard him exhale loudly, "I'm on my way. Call Dig?"

"I'm on it." She answered, disconnecting her microphone and taking off the headset.

She allowed herself 30 seconds to close her eyes and breathe deeply before picking up her phone to text their other partner in crime.

Diggle was positioned half way across the city, dressed in a green suit identical to Oliver's, ready to create a diversion if they had needed it tonight.

Her fingers flew over the screen as she typed out a message and hit 'send'.

No luck. Will explain once you're here.

Diggle's reply was full of concern and once Felicity assured him that everyone was alright, she sat back in her chair and thought over the night's events as she waited for the boys to get back.

That had been a close call. Too close. When she had realized that pink dot had been a bomb, her body had gone icy cold and she couldn't breathe. Only one thought had run through her head.

Oliver.

She took off her glasses and laid them on the table before rubbing her eyes tiredly.

"Oliver Queen, you'll be the death of me." She muttered to herself.

"I certainly hope not."

His voice spooked her. She hadn't heard him descend the stairs into the cave.

Felicity immediately jumped up from her chair, stumbling a bit as her heel caught on one of the casters that allowed her to roll back and forth between her many monitors. She quickly righted herself and shoved her glasses back on her face.

She must have looked a mess with eyes wide and cheeks flushed from his unexpected entrance.

Before fully realizing what she was doing, she rushed towards him and flung her arms over his shoulders, knocking the breath out of him as she hugged him tightly.

She felt his chest rumble with amusement before he secured his arms around her.

"I was worried." Her voice was muffled against the leather of his Hood outfit.

"I wasn't" He replied.

She tilted her head back to look him in the eye. "Are you out of your freaking mind, Oliver? You could have been blown to bits and you weren't the slightest bit afraid? That's messed up. This hero-complex thing-"

"Felicity," he cut her off and gazed down at her with a small smile tugging at the corner of his lips, "I wasn't worried because I had the most intelligent, capable, remarkable computer whiz looking out for me every step of the way."

His smile was contagious and she couldn't help but return it even though she was still pissed that he'd put himself in such danger. "Yeah, well your whiz nearly had a heart attack tonight so please be careful, ok?"

She felt his lips brush her forehead as he whispered a promise against her skin, making her shiver.

"Always."
