1846

The night he meets his sisters friend, Oliver decides he has no control over his heart.
Of course, he is to be married to a Miss Lance as soon as the ship docks, and he is aware that the Lance's are a respectful and wealthy family, but it was his mothers will that he was to marry the eldest Lance daughter, not his own.
The woman stood in front of him - he hadn't caught her name - was a contrast to the eldest Lance daughter. She was quick and witty and made strange comments that made his mother frown. But she was upfront, and held nothing back. When speaking to Oliver, her smile would become small and intimate and a blush would paint her cheeks. Oliver felt strangely comforted in the womans presence.
"When we reach New York, you must come and visit us." She had caught him in the corridor, slipping her arm through his. He meets her eyes - the same colour as the ocean - and smiles fondly at her. "I shall keep that in mind."
He forgets; once the ship docks and he marries Miss Lauel Lance, Oliver never sees the woman again.

"Miss Smoak, there are other patients to be tended to."
"Please, sir, he may not make it through the night if I don't-"
"That is the price a country must pay in war. Now leave him be."
Felicity huffs, waiting for the Doctor to turn away to another patient before turning back to the soldier in front of her. She gazes sadly at him. His injuries are severe; Felicity knows he won't make it through the night.
The young man groans. Felicity's hands seem to automatically go to his face.
"There now, Mister-" she glances at his name, frowns, feeling as though she's heard it somewhere before, "-Mister Queen. You just rest your head now. I'm sure your sweetheart will be here when you wake up."
Her stomach twists as she says the words; it breaks her heart to have to lie to these poor souls, but what other comfort could she give to these men in their last moments?
Mr Queen's hand feebly reaches up and covers her own, the one resting on his cheek. Felicity sucks in a sharp breath, waves of emotion hitting her. She sinks onto the edge of the bed, letting her tears flow freely as she watches him take every agonizing breath.
She stays until he reaches his last.

1956

He traces feather-light patterns on her pale bare back, runs his fingers through her blonde hair. She says nothing, does nothing, simply lies on her front with her arms tucked away and lets him run his hands along her naked flesh. Her blue eyes are wary when he meets them, and a fresh wave of guilt hits him. They shouldn't be here. They shouldn't be lying in an expensive New York hotel between the crisp white sheets in a drowning silence of pure guilt.
She's a married woman with beautiful children; he's the best friend and working partner of her husband. Not for the first time, he wonders why he's so furiously attracted to this woman, this angel, who can never be his.
And once again, he reaches the same conclusion; because he has no control over his heart.

2012

Oliver sometimes wonders how many lives one person lives.
He's brought it up with Thea once. She gave him a strange look and laughed at him.
"You believe in all that reincarnation stuff, Ollie? Wow. Probably means your some copy of a caveman, then."
That didn't explain, however, the odd feeling of dejavu the first time he met Felicity Smoak at Queens Consolidated, nor the strangely familiar feeling of comfort in her presence.
He's almost - almost - certain that his feelings for her are more than what he realises, that he's falling for her.
But at the same time, the feeling that he's fallen for her before.
