This is my random thoughts and conclusions On Code Lyoko the first thing is
Aelita although she lived in Lyoko a really long time, im not sure that where she started she seems to know a lot about being human and I know she had a lot of help but then there’s the little movement things she says and the way she says things, the visions she has and Taelia incident I have come to these conclusions.
One is that may be Aelita was a really girl the daughter of Dr. Heinrich and Taelia her twin sister. Now when twins are born there is a weak one and a strong on that is to say one is bigger then the other and some times that can be a big size different and one my not survive long. Maybe Aelita was the weak on and had a lot of health problems that thou she reached the age of 12 she began to Die for some reason so to stop that she was vitalized or her memories where put on to lyoko Aelita but something went wrong like government interference or some corporation with not so good work ethic killed the doctor messed with X.A.N.A causing Alitas memory loss and did something to taelia like to make here forget her past as well or something. And that when Taelia went to the orphanage and the beginning of Aelitas stay on lyoko with no memories and a messed up system that was fixing its data time is easily miss counted. Or aelita is model after Taelia and has some artificial memories as some form of experiment and it did not workout and just because she’s the mabel dose not mean she knows about it.
Well that all for know Tell me what you think and again this arm my Opinions and im a flexible person so have at them.
