Born to the Swedish immigrant Lars Lindgren and the native New Yorker Amber Smith in 1989, Amy was a child of dual-national descent. Her early childhood was not anything out of the ordinary at all. By all means, most would probably even call it idyllic. She did, after all, belong to a loving nuclear family, although she never had any siblings. While growing up, she eventually became fluent in both English and Swedish, the second coming from the summers the family sometimes spent in her father's home country, to visit her grandparents. She never had much trouble making friends as she grew up, although some of that might be credited to luck, as she was very shy at times. It was not unheard of for her to be teased as other kids found her last name to be funny or even weird, causing her to become, at times, very defensive of her heritage.
Growing up, she discovered that she had a certain fascination with water. Not only did she love to drink plain water, but Amy absolutely adored swimming and other fun activities involving the stuff. To a lesser extent, she also enjoyed going to fishing trips with her father, although she did that more because he enjoyed fishing rather than that she herself wanted to do it. Of course, they both used to throw the fish back into the water again, although they would take pictures if a particular catch merited it.
Soon after her fifteenth birthday, Amy was one day busying herself with studying for a upcoming test in school. Reading a very slow piece of litterature of which the test was partly about, she was very bored indeed. The fact that there apparently was nothing good to watch on the TV while she was taking her break did not help in the slightest. So, her eyes wandered to the half-empty glass of water on the living room couch, while her upright fingers lulled about. Suffice to say, Amy was quite surprised to see that when she moved her finger to the right, the water stirred to follow. Of course, she tested this out immediately, determining that it actually was her own actions that caused the water to move.
Afraid to tell anyone of her newfound ability, Amy wisely kept her mouth shut about it, neither trusting her parents or any of her friends with such a secret. However, she was also intrigued by the power enough to be unable to just leave it alone. Thus, the day that she discovered her ability was also the day that she began experimenting with it. Oftentimes, she would do some small-scale practice at home while at other times she would, alone, visit the lake that she and her father most preferred to fish at. Thoroughly making sure that she was alone before beginning, she would practice her ability for hours at that lake, weather allowing. She soon became proficient enough with her hydrokinesis that she could, provided she had a good source of water nearby, manipulate it freely, even sending blasts of the stuff with enough force to knock a human out. However, despite many hours practicing it, she has yet to be able to draw forth water out of the air, save for a few scant drops.
Finally, the day of the explosion came. While both Amy and her parents were lucky enough to not be caught in the vicinity of the blast or any irradiated areas, they were not so lucky otherwise. Both their home and their places of work was lost to the explosion, causing Amy's parents to be out of a job. Being homeless and unemployed in the wake of the explosion, Amy has turned to doing things she otherwise never would have in order to survive, such as stealing. She has also taken to carrying a knife on her person, just in case, but has as of yet not even needed to draw it. While it is safe to say that Amy has heard of the Linderman Act and what it entails, it appears that she does not care; being homeless seems to have made her think she does not particularly need to worry about government agencies clamping down her non-existant front door to register her. As far as she knows, no one but her knows of her ability thus far, as she has been very secretive about it.
