[contains massive spoilers from the unseen avenger series]

EARLY LIFE

Isabelle Grace Sprouse was the daughter of an Italian immigrant and a New York stockbroker, who's marriage was not happy after their first few years together. Desperate to get away from her parents' toxic relationship, she'd find a job in the CIA. David Theo Firman was the son of a Filipino couple who risked everything to have a life in America. They gave their son a very American name, hoping he wouldn't be victim to as much racism as they had experienced. David's parents would pass shortly after he graduated high school and joined the Marines, where he would eventually be recruited by SHIELD.

David would go onto be stationed in Florence, Italy. He would meet Isabelle when she took a three week break from work to see her extended family in her mother's homeland. After meeting in a bar, they would have a short love affair before Sprouse arrived home, neither really knowing much about the other.

Sienna Isabelle Firman was born on February 18th, 1990 somewhere in Washington state to Sprouse nine months later. Sienna is believed to be Isabelle's fourth child; she had twins Zerina and Xander(who died within a year due to heart problems), and daughter Nya. Isabelle never married, leaving each child with the father once the baby stopped nursing.

A young Sienna was given to her father upon her next trip to Italy. She would spend the first five years of her life in Italy before her father was transferred back to a SHIELD installation in the US. Despite long missions away from his daughter, David always found time to visit her whenever available. Their relationship was a very loving one, David always trying to compensate for Isabelle's absence. Her early childhood was about as normal as you could get with no mom and a hard-working father.

When Sienna was seven years old, she was kidnapped by unnamed rouge agents who wished to get back at Agent Firman for past faults. David arrived before his daughter was hurt, but was greatly over-powered. A young Sienna got to watch her father's guts being ripped out of his body as the men extracted their revenge. SHIELD reinforcements arrived in time to eliminate the threat and get David to the nearest hospital. By the time they arrived at the emergency room, he had bled out, his last words telling his shaking daughter he loved her.

After a long process to get Sienna relocated, Isabelle took custody of her. Accounts of the mother's previous behavior showed her never having a history of alcoholism, but shortly after Sienna arrived, she started heavy drinking. This could be due to David's death, even though she never showed explicit feelings for him after their daughter's birth, but she also was expelled from the CIA under accusations of being a double agent, though it was never confirmed. Her alcohol addiction led to Isabelle abusing Sienna for the better part of a year.

When Sienna was nine, it seems she accidentally killed her mother. The young girl got a pistol off Isabelle's hip during a drunken dispute between the two. She intended just to scare her mother, but she was not experienced with firearms and pushed to hard on the trigger. SHIELD was notified and Agent Phil Coulson comforted a shocked Sienna as Isabelle's body was dragged away. Instead of putting her into foster care, SHIELD took her in under undisclosed circumstances.

It has been reported that Sienna dealt with mental illness throughout the next few years. When she started training at a very young age, she continued to fall at the bottom of the roster and began to see a specialist for therapy. Director Fury insisted to keep her in the program, even when it seemed as if her struggle with depression was greatly inhibiting her growth as an agent. Through time it did get better, but the experiences of both her parents' deaths still weighed her down.

At fifteen, Sienna was sent on her first official assignment. It was supposed to be easy, talking to Agent Clint Barton after he'd gone off the radar while pursuing assassin Natalia Romanova. Instead of finding Barton, she found Natalia, who assumed she was a Red Room agent sent to bring her in. After taking four bullets to the stomach from Romanova, Barton was able to patch Sienna up and convince her that the Russian murderess was indeed a potential asset. When they arrived back at SHIELD, Clint volunteered to become her SO. Sienna grew greatly under Agent Barton's teaching, and within two years became was promoted several times, passing far more experienced agents. Strike Team Delta was formed soon after, consisting of Clint, Sienna, and newly named Natasha Romanoff. Sienna eventually forgave Natasha, and the team completed over fifteen successful in the course of the year.

Agent Firman was then sent on a mission alone to take on Thomas Qade in which-

Sometime in early 2010 when Sienna was nineteen, she relapsed into depression under unknown circumstances. She also became very anemic and took a three month leave from SHIELD to recover. She seriously considered leaving the organization, but decided against it while on leave, finding it impossible to relax. Having only know a home at SHIELD for the last decade and realizing her growing PTSD wouldn't allow her a normal life, she cut her vacation short and returned to active duty. When she arrived, her entire demeanor changed and she became so immersed in her job and life as an agent, some would describe it as an obsession. Yet she still surpassed many of her peers in skill level due to being so dedicated.

One of her most notable missions was the single-handed take down of Edward Valdez's illegal trafficking of prototype weapons, all under two months. While doing so, she went undercover as a secretary at Dane Global, the international company Valdez used as front. Within a five weeks of being there, she befriended and became engaged to Andrew Dane, CEO and tabloid legend for having the 'Five Day Marriage' with actress Lolita Reese. They did become married, but it only lasted two weeks when the mission ended, making it Dane's second shortest wedlock scandal. It was unclear if Sienna ever had feelings for him.

A few months later, Sienna was briefed on the Avengers Initiative and sent to recruit billionaire Tony Stark, also known as Iron Man. She was the agent charged with observing him through the process and was Agent Romanoff's back up when the Hammer drones attacked. She also assisted Barton in New Mexico when Thor was apprehended, and she engaged him. The fight left her hospitalized for a month.

Sienna, after working closely with potential Avengers, submitted herself for the Initiative in hopes her impressive service record would give her a position. She was the only potential candidate that was immediately rejected by Fury. Instead, she was assigned to the Tesseract base with Barton just as the object opened a portal to outer space.

APPEARANCE

Sienna is described a Filipino woman with an athletic build and angled Italian facial features that seem to change with whatever facade she puts on. She has long dark hair with oval-shaped warm, brown eyes. She is around 5'8 height wise and is almost always wearing heels. She is said to be a quite striking woman, and she carries herself with a rare confidence and grace that does not hint at any weakness. Yet the entire way she presents herself can be replaced in a moments notice.

PERSONALITY

Sienna's true nature is not known by many. Those who do know her describe her as dedicated, headstrong, and loyal until the end. She can also be defined as bitter and often very business-like, but does have an impulsiveness that can sometimes find her in troubling places. She has a distaste for sarcasm, she finds it unnecessary, yet she still has a sense of humor and surprising wit about her (let's not forget the puns). Sienna is a naturally reserved person and has trouble expressing emotions, but that does not mean she doesn't have deep ones. Her choleric nature makes her a natural leader, but she does crave control, which can lead to selfishness. She's very hard on herself, but does rejoice in the small victories when she can.

Whenever Sienna is prohibited from work or unable to do her job correctly, such as when she is detained in hospitals for extended periods of time, Natasha sums it up best by referring to her as 'an obsessive, paranoid, lethal workaholic'. Her life at SHIELD is all she really has, and she pours everything into bettering her skills as an agent.

quotes

"You know what? I'm not going to. You don't have the authority, Captain Rogers, to order me to do anything. I suggest you stop acting like you do.....Either way, I'm coming with you."

"We all have our caged lions, our hidden truths. They claw at our ribs as they try to get free, and sometimes they win. Sometimes the truth you've tried so hard to bury destroys you from inside it's own cage."

"I'm a spy. I'm a professional at knowing things I shouldn't."

"I can speak eight languages, and I'm pretty sure 'no' doesn't translate to 'convince me' in any of them. I said no, end of story."

"None of you get to control me. Not again. This is the part where you start running."
