I listened carefully to the g/f's extended length statement last night and I caught this very interesting exchange. The interviewer was constantly leading her, and here, she seemed confused as to what he "wanted" her to say:
"14:49

Interviewer:"Did he ever say the guy got out of the car?"
GF: "You want that too?"
Interviewer: "I want the truth"
Again at around 16:00, she seems to be looking for guidance as to whether or not Trayvon said he was going to hit this guy.
When asked what Trayvon told her he bought at the store, she said "iced tea". He did not get iced tea, he got Arizona watermelon fruit juice. The iced tea, for whatever reason, was likely made up by the Martin's and Crump.
