Meg T. was a CTU intelligence agent active during Day 4.
While he was getting ready for the hostage exchange with Habib Marwan, Edgar Stiles forwarded the LAPD hourlies to Meg for her to review. She was overloaded but Edgar insisted, so she looked through for any flagged items of importance. She found the report on the unusual disappearance of the family of Air Force pilot John Hansen, and gave Edgar a CD with her findings. Since Edgar's workload was booked, he couldn't review the information in time, allowing Mitch Anderson's impersonation of Hansen and his theft of a stealth fighter to continue unimpeded.
