As a child of Poseidon, it's no surprise Finley's mood changes with the crashing of the waves. He can often be found in a pissed off mood because of one thing or another, and it's really not hard to get on Finley's nerves. Hell, even his father has told him to cheer up before, which is shocking considering the God's own temperament. Finley is happiest when he's in the ocean, and it's about the only time you'll get a genuine smile out of him - it's where he feels safest and most able to be himself. His moody demeanour doesn't make Finley an inherently mean person, however, and he is still capable of emotions that aren't so negative, it's just rare for the boy to go a day without giving out a few glares and eye rolls.

Finley upholds strong morals, and is not one to be swayed. However, what he believes is 'moral' may not be exactly what others may qualify under that category. Finley will do anything for the ones he loves, and has no qualms when it comes to using his abilities in order to protect those few people. He isn't a particularly selfless person though, and so wouldn't do this for just anyone nor would he jeopardise his or a loved ones life in order to save a perfect stranger. The only way Finley could be pulled into the darkness that dwells just under his surface, is though manipulation with his family or close friends. If he believed they were in trouble, Finley would do anything to help them, no matter the cost.

Due to his secretive nature, if there was ever anyone you could confide in, it's Finley. No amount of prodding or begging could get Finley to spill his, or anyone else's secrets -that is unless you used the tactics previously mentioned, even then it would be an internal struggle for the guy. Losing someone's trust to protect someone else, it's a sticky situation for him to be in. His trustworthiness is something Finley truly likes about himself, which is saying a lot considering he certainly doesn't hold himself in the highest regards, meaning that to lose the trust of someone he has promised to protect, would shatter his cold heart.

When first meeting Finley, the immediate thing you will realise is just how sarcastic he is. His sense of humour is incredibly dry and he tends to deadpan a lot, which is not to everyone's taste. Finley genuinely doesn't mean to come across as somewhat unapproachable, but his sarcastic ways certainly don't help him much. People often think he's just being rude, not aware that Finley is trying to joke around with them, in his very own bizarre way. This has only fuelled his belief that people just don't really like him, and therefore he has become more standoffish and icy.

Finley had a fairly idyllic upbringing. Living right on the coast in Sydney, Australia, he was able to visit the shore anytime he wanted. His mother was unbelievably doting on the young boy and even his step-father - Steven - was a great guy, he treated Finley just like his own son and they formed an extremely close bond. No one ever mentioned Finley's biological father, and so the young boy never really thought about it. He already had a family, he didn't need anyone else.

Growing up, Finley was a happy, rambunctious boy, worlds away from the closed off and moody young man he is today. However, his love for the ocean has never wavered. Lillian, his mother, had lived her whole life surfing and sunbathing, so it seemed unsurprising that Finley would follow in her footsteps - whilst unknowingly also following in his father's. Everyday when he arrived home from school, it would be a race to get into his swimwear and get down to the beach in time so that he was able to surf until the sun set.

When Finley's mother fell ill, just a few weeks after his seventeenth birthday, the boy shut off. She was his lifeline, the one person in the whole world who he entirely adored. Steven tried his hardest to comfort the boy, but it wasn't the same. This was the first time Finley longed for his biological father, someone who - he hoped - could fully grasp his anguish. As months passed and the woman's health deteriorated, Finley only grew increasingly more hard. He began fighting with his step-father over the care his mother was receiving, Finley never believed that anyone cared as much as him and so the doctors and nurses weren't doing their jobs well enough, in his eyes.

Lillian remained her same old positive self, while her body began to fail her, her soul stayed as radiant as ever. Whenever Finley thinks back on this memory, he realises why it was so easy for Poseidon to fall for her. No one cared as much as Lillian did, about anything - her family, her friends, even the strangers on the street, if she could help them then she would do everything in her power to.

The first time Finley met Poseidon was out on the ocean. He had chosen to surf on a particularly stormy day, the kind of day where no one else was out on the water because it was far too dangerous. Finley didn't care though, his mother had been moved to a hospice and he knew exactly what that meant - she wasn't going to get better. Eyes trained solely on the water, Finley marched right into the crashing waves, his gaze steely and jaw tightened. He needed this escape.

Unsurprisingly, just a short while after entering the water, Finley was dragged under. He had been surfing an exceptionally large wave when it crashed over him, dragging the boy down into it's depths. Catching his left arm on a jagged rock, Finley was cut from the top of his collarbone down across his left bicep, cutting into a major artery. He would've bled out in the water even before he'd drowned, if it hadn't been for the abilities his father had gifted him.

The last thing Finley remembers before losing consciousness is a large man coming toward him, thick dark hair swirling around him in the water. Waking up on the seashore, Finley noticed the large gash on his arm had healed to a pink and slightly irritated scar. Already? Attempting to shake the feeling that something was off, Finley accepted it, rather than question it and was simply happy to still be alive. It was then he realised that he could never leave his mother, not like this - and that doing what he had done, attempting to surf in a storm was just selfish and impulsive. He'd been too reckless these past years since his mother's illness first began, not thinking about anyone else's feelings but his own.

Resolving to be a better person, at least for his mother, Finley apologised to his step-father for all the hurt he'd caused him. They then spent his mother's final months together, and they were as happy as they could possibly be during a time like this. Leaning on someone else for support rather than bottling it all up was much healthier,
Finley found, and he vowed never to hurt anyone like he'd hurt his mother and Steven these past few years.

Passing the night before Finley was due to turn nineteen, Lillian had lived a long life for a person in her condition. She died surrounded by her beloved son and doting husband, and while the pair would shed many tears of grief, they also knew she was in a better place.

One year later, while Finley sat in the sand, letting the cool ocean water run over his feet, that same man who saved him years ago appeared once more. Taking a seat next to the young man, Poseidon began to tell Finley about how he had met Lillian, recounting their summer together. He had loved her but just like any other Deity, Poseidon couldn't stay with her forever. He'd always watched over his son, seeing him adore the water just as much as his mother had. Finley's sadness became entwined with happiness as he listen to Poseidon recount his story.

Finally, he told Finley about a camp for demi-gods, urging him to go and find others like him. Informing Finley that he had a sister who would also be attending, the young man found that he couldn't say no. He had a sibling - and a sister at that. It may have been wrong, but Finley hoped to form the kind of connection he had with his mother with his new sister and so, he told his step-father that he was going to travel, needing a change after his mother's death and set off for Camp Athens.
