Sounds like a teenager, a brainwashed Muslim, a brainwashed evangelical, and lawyer induced all at once (not quite as bad as a brainwashed antiMormon though ). However, if her story is true, that she will be killed for this is quite plausible. If I were the state, I wouldn't risk it (returning her).
Is it an act? I have a similarly aged daughter (a cheerleader too coincidentally) who dramatizes like this and if this girl really feels her life is at stake, she's underacting.
On my Mission I met some Pakistani Christian refugees. While it varies there can be a real danger. We had one muslim convert who was threatened with death in my Mission. With the help of some friends he fled the country and I heard he was changing his name.
