"I knew this would happen." Felicity thought as her nails clacked against the computer keyboard in front of her with a little more gusto than normal to block out the sounds of Oliver Queen and Sarah Lance kissing on the sofa.
"Honestly, you come back from the dead once and suddenly everyone wants to get with you." she grumbled with a visible role of her eyes. Felicity heard a snigger quickly covered up by a cough. She swivelled around on her computer chair to see Diggle standing in the corner of the room with his hand over his grinning mouth. He had seen her indignation over Oliver's antics and obviously thought the same. She smiled back knowingly.
"What are you two smirking about?" asked Oliver, taking a short breather from the snogging marathon he had just taken part in.
"Nothing!" said Diggle and Felicity at exactly the same time. Diggle went back to searching on his phone and Felicity turned back to the computer screen, finishing the local surveillance of CCTV cameras; a new habit of hers considering what was going on.
"What you doing?" enquired Oliver, who had suddenly appeared behind her, nearly making her fall out of her chair.
"Jesus, Oliver! Can you at least tell me when you're going to creep up on me? I swear to God you're going to give me a heart attack one of these days!" gasped Felicity.
Oliver smiled a coy smile and then looked back to her screen.
"Why are you looking at security cameras?"
Felicity blushed and turned away from him. "It doesn't matter, just peace of mind."
Oliver saw her turn away from him and was immediately worried. This wasn't like Felicity. She normally would think of some incredible lie to explain her actions but not tonight. Now he thought about it, she had been looking tired recently. Studying her face carefully he saw dark blue circles under her eyes implying a lack of sleep. "Are you okay, Felicity?" he said quietly, kneeling down to her height so he could look into her eyes.
Trying to ignore his closeness to her, Felicity mumbled "Fine," before flashing him a quick smile and turning back to her computer screen. She definitely didn't note how blue his eyes looked in the low light or how his muscles seemed to ripple underneath his tight black top. She closed off the CCTV camera tab, shut down her computer system, grabbed her coat and quickly excused herself from the room.
Sarah was still sat on the couch, watching her leave then looking back to Oliver, tempting him to come back. Normally, he would be by her side in a flash when she was like this but he was too worried about Felicity to even notice her. He crossed the room to Diggle in a few long strides and whispered, "I want you to follow Felicity home. She's been checking the CCTV cameras near her house and she looks like she hasn't slept in weeks."
Diggle looked at him for a few moments then nodded. "Don't worry about it, I'll look after her." Oliver slapped him on the back, relieved that she would be safe.
He walked back to the sofa and snuggled next to Sarah but ignored her attempts to gain his attention. He was too preoccupied worrying about Felicity. She was normally so sarcastic and energetic, a little too much sometimes, so something big must be on her mind. But what could it be?
