she's turning the whole thing into something much bigger by probably purposely not making any effort to get out. If she really felt so distressed she would have bothered to try and do something, its not hard to work out, its common sense

Airside can be a dangerous place to wander around for those unfamiliar with it and if security got as upset as they did to find her on the plane just imagine what they might have done if she had been wandering around outside.
