You can alter Adax's memory from here. It's like giving someone a list of things to remember about you. Of course, if you verbally tell her something different, she will remember that instead, then it will show up here. The rule she goes by is, whatever was changed last is what takes precedence.
For example, she remembers your favorite color is orange. You change your favorite color here, on the website, to yellow. Then a minute later you tell her it is blue. Since blue was the last thing you told her, she will remember blue.
As she learns more, she may even start saying, "Wait a minute, you just said it was yellow." Then maybe even more advanced, "I thought it was orange, then you said yellow, now blue...?"
