If it happened the way they think it did and from what the cell history indicates she was incapacitated at 7:26 when they pulled out from beside his moms place and didn't regain consciousness until she was engulfed in flames. Coming to from being engulfed in flames I wouldn't necessarily expect her to remember what had happened in the preceding 45 minutes or so. She knows her name and can express her condition (cold and thirsty) but I can see where she might not have been coherent enough to name QT as her emulator. Another ridiculous thought that I can't shake and as improbable as it sounds, maybe even after what he did to her she was too intimidated to snitch on QT. I'm reminded, if what they say is true, eight months later he was torturing the girl in LA with a knife in a attempt to get her pin number. The guy is worse than an animal.
Adding to this train of thought, it is possible she was with Eric when she was rendered unconscious, woke up engulfed in flames in the car, therefore Eric was the last person she remembers being with and assumed it was him. Just my theory.
