Derek was the first of the siblings. He came from their mothers first marriage. When his mother divorced his father and soon married husband number two (Allies father) was when he gained a little sister. The two share completely different last names as they were given their fathers. They both took after their mother in looks though. Brown hair and brown eyes. No one would suspect they were from two different marriages. The siblings were close, as any normal brother and sister they fought a lot when they were younger. Allie being the annoying little sister that just wanted to be around her older brother, always bugging him on what he was doing.
When Allie turned the age of 6 they found out her Father had cancer, too far gone for treatment to really work but it would prolong his life. The family went through 3 long years of pain and heartbreak before the cancer took him from them. This was the first of many tragedies in Allies life, and what many believe was the stare of her odd behavior. She started talking to what doctors called 'an imaginary friend'. They ran all sorts of tests on her but found nothing wrong when it came to her brain. So most just thought it was a phase she was going through from the loss of her father. From then everyone just kind of ignored her behavior until she started lashing out violently. She would snap, throw things, hit her mother and her brother to the point where they needed to restrain her. They did the normal things, she was sent to talk to a shrink and put on medication that seemed to help but as the years went on she kind of developed a defense mechanism. She would talk as if she was still a young child. Mainly using it to get her way, or get away with things she had done.
Her brother was the only real support she had. He would listen to her. Try to understand what she was going through, while her mother was too busy with work and dates to even give her the time of day. Knowing her mother had just grown tired of dealing with her. When Allie hears the voices in her head there are three different ones. Each one can come forward and gives Allie different ideas. There is a child like, playful and carefree who just wants to have fun. Then there is the calm, normal, laid back voice who just wants everything to remain calm. It is on edge sometimes and on guard but it doesn't look for trouble, Then there is the final voice...The one that has haunted Allie since she was younger. This one is named Linna. This voice taunted Allie when things get bad, but at the same time was the only 'person' she felt she had to talk to when she grew up. Whenever something happens and Allie becomes too confused then Linna will come forward and take over to keep Allie safe. Even if it means turning on her friends.
When it comes to her mother, she wasn't exactly the 'best' mother figure. Having divorced Dereks father and ended up marrying her father who ended up dying of cancer and then finding husband number three all the way on the other side of the world. Not to say her mother wasn't a good person. She was a surgeon. A really good one at that. She just grew tired of Allies condition and wanted to live her own life instead of dealing with her mentally traumatized daughter, so she left that to Derek. Allie looked up to her mother regardless. Always interested in the work that she did saving people. With all the moving and new guys coming around Allie started to see that her mother really didn't seem to want her children around. Her brother starting to see it first and was the only one to show concern about what was going on.
That was when her mother started online dating. Seeing as she couldn't bring people to the house with Allie acting out. She only talked to this guy for two months before she decided to pack up everything and move. The man had money, Allie wasn't stupid, and neither was Derek. It wasn't until they moved in with husband number three that things went from bad to worse. The siblings never knew what their step-father did for work. All they knew is it brought in money, a lot of it. It also meant he would come home drunk from work, and Allies behavior wasn't what he accepted in his house. Leading to him having hit the girl a couple times out of anger, and getting Derek into a couple fights with the older man, losing, but sticking up for his sister.
Their current 'father' came home sick one night after work. Their mother simply said he was catching the flu and he would be fine in the morning. Yet when morning came the siblings woke to their mother bloody and beaten on the floor of the living room....and their father...no....something else standing over her. It had been so long since Allie had seen any love in her mothers eyes, but looking at them now filled with tears as she lay there staring at her two children with enough strength to tell them to run made Allies world crumble.
With a growl the taller male turned on the two of them and they ran as they were told. That was when the outbreak started to spread. Within weeks more and more cases of people getting 'sick had started popping up. After a little over two weeks the dead walked. Allie and her brother have taken to hiding from not only other people but these 'zombies' Having watch her father die slowly from Cancer, and seeing her dismembered mother it was no surprise that Allie went into a complete emotion break down. The world was dying, the dead were walking. It was all a really bad dream, so her brain registered as just that...a bad dream. Allie's 'normal' self hide inside the back of her mind. Pushing forward a emotionless like manner in a way to not accept the reality. She will be seen mumbling nothing or just saying the same words over and over. A lot of the time she's spaced out looking at nothing. She doesn't talk much when it comes to strangers. Not even telling them her name. She will also sometimes talk in 3rd person when addressing herself. Her brother Derek had slowly come to accept that he can't bring his old sister back and just tries to keep her safe and calm, as any kind of stress will lead to and outburst and another break down.
Extra Note: She has a mild form of kleptomania. Mainly medical supplies. Due to how they remind her of her mother. Anything medical she takes instant interest in before stuffing it into her bag.
Allie is a mixture of a mess, when she is calm and normal, appears to be quite pleasant, nice and sweet. She is indeed capable of being very logical when she is not overwhelmed by emotions. Though due to the traumatic events of her life and becoming partly damaged, she is often a bit odd, occasionally making inappropriate comments and throwing tantrums. These have proved to be some of the lesser problems she created, though, because when she was having one of her mental outbreaks, she may commit dangerous acts and is potentially a threat to everyone. Allie can be the most pleasant person you meet. However she is not one to be pushed around and walked all over. She is strong, independent and quick to say what's on her mind no matter how harsh it may be. She isn't one to beat around the bush to spare someones feelings.
There is one particular voice in Allies head that is a separate person completely. This personality is vengeful, ruthless, embittered, cold and calculating. She will turn against her closest friends and even her own family, This side of Allie zealously pursues what she believes to be her play time, consisting of torture and even death to even those she cares about. Despite her vindictive and unforgiving personality, however, This side of Allie remains a powerful, arrogant, intelligent, overconfident, and ferociously determined individual. When it comes to Linna she is the one that will slice your throat without so much as a blink of an eye. Linna is Allies defense when things get too hard for Allie to handle. You MAY be able to speak rationally to Allie...Linna doesn't give a shit.
