The text during Area 9 White Hundred Main Quest's Cinema Talk includes a part where Ava plays a sound that the player (your character, definitely in the teens), Henryk, and Ava can hear. She notes that only people over 30 can hear the sonic wave. This cannot be the case for two reasons.
- She proceeds to insult Henryk about being "over 30 with a face like that" implying he looks way older than he is. If he is older than 30 there is nothing wrong with his aging face in that sentence. Thus in the insult it should be "You claim to be under 30 with a face like that?"
- Your character can hear the sound. These sonic waves Ava used to play were for young people, which you could hear. If this one which is slightly lower in pitch is one you can hear too, and your character is a teenager, then the sound wave should be for people under 30 not over.
Therefore, it seems logical to conclude that there is a mistranslation of over and under in the dialogue.
Note: However, this is also strange because previously Henryk admits having a mistress and daughter, and Lex implies he is middle-aged. If we conclude instead that Henryk is indeed over 30, then the last line Ava says should instead be "You claim to be in your thirties" to make the insult work.
