Is there any way to stop her?

I don’t know if this is the right feed for this question but it’s worth a shot. My grandmother has been courted by JW for close to a year now and she has gotten in deep. She plans to be baptized by the end of this year. I’ve managed to raise doubts in her; even got her to change her mind for a little while. But every time she has questions they manage to reel her back in. I know she’s so much smarter than this but I can’t shake her loose! I’m planning on visiting her for a few days next week and am going to try one last big push. Any thoughts or ideas that might help? Any articles or interviews that I could show her?

(I promise I’m not a bot. I’m mostly a Reddit lurker but I’ve run out of places to turn.)
