GoingThruTheMotions - Casually ask her if she knows how long King Jehoiachin of Judah ruled for.
Answer is 3 months 10 days.
Then ask her if she thinks the scripture below is talking about the 8th year of King Jehoiachin or the 8th year of Nebuchadnezzar.
(2 Kings 24:12) . . .At length Je‧hoi′a‧chin the king of Judah went out to the king of Babylon, he with his mother and his servants and his princes and his court officials; and the king of Babylon got to take him in the eighth year of his being king. . .
If she starts to reason with you on this you are potentially only 6 scriptures away from getting her out. Or at least getting her to annoy the elders with questions they can't answer. Hey you might even get the elders out.
If you want further info please see the website I put up to prove that the GB are apostates. This is the explanation page:

I hope to put up a clearer explanation at some point, meantime this is the best I can offer.
