I listened to the whole conversation and agree with some of the posters who said she talked too much. However, she used some JW terms that the Watchtower people may have picked up on and quickly identified her as an ex-JW. In her conversation she used the terms "brother" and "elder" instead of Watchtower spokesperson, She used the term "meeting" instead of JW services.
My guess is that because she used JW language, the Watchtower guy k he was talking with an "apostate," and was more closed mouth with her than he would have been with a non-JW.
While a non-JW would have gotten the same answers, the Watchtower spokesman would not have had the satisfaction of thinking he was defending the Borg from "apostates."
