The question that I have is whether she was really tall in her profession? She is portrayed as tall in the comic books, films and TV series and by most online fans of the game, she is supposed to be in the same rank as her colleague Coraline Jones. I would say that it is very unlikely for her to be anything other than at least 6 feet, even if her height fluctuates in-game.
Despite this, I believe that this issue is not the case when it comes to real life. There are many people in the real world who are not even aware that they are indeed slightly shorter than the people around them. For example, I have friends who are extremely tall and yet have not a clue about their height, which to me is very weird. Then there’s the taller colleagues in the profession, who clearly don’t have problems with their height but can see people of a lower height having a hard time fitting in. So I think it is much more likely that young Coraline Jones was simply given an advantage through her profession.
In the film, Jonesy is shown to be quite a tall figure, which I found rather odd. However, it does fit in with her character and I am sure many other female characters throughout the ages have been given an advantage similar to Jonesy. If Jonesy had been a really short woman then I’m sure the producers would have worked harder to give her an advantage in height. It’s just one of those rare moments in the animated world where reality is brought into play although it is more than likely that they have been told to do this.
