Oliver stood in the kitchen, glaring at the space before him. Did that really happen? Was that even possible? Maybe Barry had hit his head so hard that he was hallucinating, Oliver dismissed the thought, he'd had worse blows and he'd been fine. He turned and looked out into Felicity's apartment, Barry was nowhere to be seen, but her front door was open.

Oliver pulled his phone from his pocket and called Diggle, walking towards Felicity to check she was okay. She was still asleep on the couch, her mouth slightly open, her chest rising and falling gently. She looked beautiful; this was the Felicity he never got to see. Make up free, calm and for once, not babbling although Oliver liked her babbling.

"Diggle," Oliver said, walking towards the front door and closing it. "Remember when I said we couldn't trust Barry?" Oliver heard Diggle sigh.

"Vaguely. You only mentioned it a couple of hundred times."

"He's not human." Oliver rolled his eyes at himself, realizing how ridiculous he sounded. "He's like the men I fought on the island. He's been modified, only not with strength."

"What are you talking about?" Diggle asked confusedly.

"He's fast, faster than humanly possible." Oliver said. "I need you to go to the basement, get on Felicity's computer and track his phone." He ordered, hoping that Diggle had grown competent enough to access Felicity's software. It was beyond Oliver but she'd watched her teach Diggle. "Find out where he is and keep an eye on him. We're going to get him in the morning."

"Okay, what about Felicity, is she okay?" Diggle asked.

Oliver looked back to his sleeping IT girl, "She's not to know about this until we find him." Oliver heard Diggle hesitantly agree and he hung up the phone. He wasn't going to leave Felicity tonight, not when Barry could come back at any moment. He was going to protect her, even if he had to go behind her back.

Oliver bent down, scooping Felicity into his arms and hearing her sigh contently. She nuzzled her face into his neck and Oliver felt himself relax. She smelt like vanilla and coconut, two scents he'd never really been fond of until now. The scent comforted him, assured him.

Felicity's bedroom was wallpapered and cluttered with posters, books and a couple of strange figurines. The room smelled like her, her bed sat in the middle of the room, a purple duvet with white spots laid on top. He smiled when he saw the small unicorn plush sitting between her pillows.

Oliver looked down to Felicity, taking all the time he could get, holding her this close to his body. He saw her for her real self now, he saw some of the interests she'd never shared with him, like how she admired Elton John, she had a poster of Elton on her wall, he wanted to protect her now more than ever. She was too precious to lose.

"Oliver?" He heard Felicity mumble and he smiled, realizing she was talking in her sleep. He quickly carried her to her bed and placed her down. "Oliver?" She said again starting to wake up.

"Hey," Oliver whispered, giving Felicity her unicorn, "Go to sleep, I'll be here when you wake up." He watched as her eyes slowly flickered closed again. He brushed her hair from her face as she sighed.

"I missed the end of The Grinch." She mumbled which caused a quiet chuckle from Oliver to sound.

"We can watch it later, Felicity." He looked around the room for something to cover her with. He wasn't able to pull the covers down before, so she laid atop of them and he worried she would be cold. He found a brown, quilted blanket on her armchair in the corner and draped it over her. "Goodnight." Oliver said, lightly stroking her face once more before settling into the armchair in the corner of her room.

Felicity Smoak stirred in her bed, she wasn't confortable because she felt something moving against her stomach. She rolled on to her back, trying to get comfortable once more but it was a useless exercise. She sat up flustered and gasped, seeing Oliver asleep in the armchair opposite her bed. His eyes shot open and he was by her a second, a groggy but worried look on his face.

"Felicity," he grabbed her shoulders, "What's wrong?"

She sat there staring at him, wondering why he was there. Why he chose to sleep in her chair. Why he'd stayed over. Had something bad happened? Felicity hugged her blanket around her self, "What are you doing here?" She asked, feeling that strange tingle cross her stomach again, she ran her hands over her belly realizing she'd left her phone in her pocket and it was vibrating. She pulled it out, eyeing the name on the bright screen. "Barry?" She mumbled, but wasn't he in her guest room.

Oliver's eyes widened, "Don't answer that!" He said, reaching for the phone but Felicity pulled away.

"Hello?" She answered her phone, giving Oliver a strange look as he ran his hands through his hair in exasperation.

"Hang up the phone now, Felicity." Oliver warned, "He's not who he said he was."

Felicity rolled her eyes, "Barry?" She asked, "Are you okay?"

"Felicity," Oliver grunted impatiently, "If you don't hang up that phone right now, so help me god."

"Sorry, Barry, one second." Felicity covered the speaker on her phone and glared at Oliver, "What is wrong with you?" She asked, moving out of bed towards her bathroom. Barry needed to talk to her and she couldn't concentrate with Oliver's moody outbursts.

"We can't trust Barry!" Oliver called, coming up behind her and pulling her phone from her hand.

"Oliver!"

Oliver held the phone to his ear and took a deep breath. "You better watch out Allen, I'm coming for you." Oliver said, "I might just have an Arrow with your na-'' Oliver paused and looked at the phone. Barry had hung up on him.

"What is your problem?" Felicity yelled, "What happened to Barry? I take it he's not here." She folded her arms as Oliver closed his eyes, pulling his thoughts together.

"Just," He let out a controlled breath and steered her towards her bed, "Sit down."

Felicity complied, watching Oliver warily as he sat down next to her.

"Barry lied to us, Felicity." Oliver said and before Felicity could interject he took her hand to silence her. "He's not human."

Felicity gave him a puzzled look. "I don't understand."

"He's different, one minute he was in the lounge room, running at me, the next he was in the kitchen." Oliver explained, realizing that Felicity was looking at him like he'd gone crazy.

"Why was he running at you?" Felicity said and Oliver rolled his eyes on the fact that his argument was the only thing she'd gotten from what he'd just said. "What did you do?"

"Nothing!" Oliver explained, why was it that since Barry Allen had waltzed in that she assumed Oliver was always the one to do wrong. "You fell asleep and I was gonna take you to your room and Barry said he would and got up in my face about it so I pushed him and he went to run at me and…" Oliver looked into space, recalling the evening's events, "I guess he missed, but he ended up in the kitchen in a split second. It is not humanly possible to move at the speed he did."

"So, what are you saying?" She asked, wondering if the rat poison Barry had cured Oliver with days ago was still in his system, "He's got superhuman speed?"

Oliver nodded, "Yeah, that's not the most of our problems though." He said, looking back to Felicity with grim eyes, "Remember when he told us that the night his mother died, someone moved through his house like a blur?"

Felicity nodded, wondering what Oliver was getting at.

"Felicity, what Barry explained, that blur. I saw it tonight, it was him. I think Barry killed his mother."
