Continuity mistake: Ellis leaves in in his dad's Jeep (model year 2005-2007) and in the very next scene he is driving a newer model.
Continuity mistake: Adaline takes the glass of liquor from Ellis' hand and finishes it. Once she walks out the door the glass is next to Ellis again, and when she appears outside it's filled again.
Continuity mistake: Adaline takes a glass filled with some liquor from Ellis' hand while he is on the phone and she walks out with it, but in the next shot we see that same glass back on the counter beside Ellis. (01:17:15)
Continuity mistake: When William meets and helps Adaline with her car the sun changes between shots.
Chosen answer: It was because she had used so many fake I.D. the F.B.I. had become suspicious, possibly believing she was involved in some type of criminal activity, which is often why people assume different identities.

No, that can't be right because she doesn't start using fake names until AFTER the incident with the FBI. She was still using her normal name, Adeline, when the FBI grabbed her. The implication of the story is that they grabbed her because she didn't age and they wanted to use her as a lab rat.
