Couple more observations...
The flight happened last month and she's just now making waves? Granted, it could have taken some time to get traction in the media but a cursory search turned up no stories older than two days. Why the long delay?
Also, I'll give her the benefit of the doubt and presume she was too shocked to act in anything remotely resembling a rational manner. However, this also has to presume she was unable to act on any nunber of potential notifcation vectors: tell someone directly, show them the text, mutter something over and over again, etc.. Heck, even rocking back and forth in the seat with a blank look on her face would likely have gotten flight crew's attention. ("Captain, passenger Cray Z. Planebommer in seat 4C is acting strangely...")
Finally, where's the text? If I were on her side of this I'd be flashing a copy of the text all over the place. Again, I play devil's advocate and presume she deleted them accidently. Or maybe lost her phone. Whatever. There's still the option of retrieving the messages from her service provider.
The more I think about the situation more fishy it seems.
