So the plot points I remember are that this girl is taken by the main protagonist group of the film/series, and she has value to them. There’s this French guy that’s the tech expert of the team, I was convinced it was Saïd Taghmaoui but it wasn’t him, and he ends up being her guardian in a sense, like a protector. He spends most of his time with her trying to get her to talk and eventually she does communicate with only him. She also sacrifices herself for him I think if I remember correctly. This guy also has like a girlfriend or a main partner that’s a female. I also seem to remember there’s like a mind communication element or like a special language she made up but I could be mixing that up with something else. This is killing me so I hope someone can help.
