I'm not surprised that's what she (and many more J.W.'s) believe, based on the G.B.'s recent Watchtower propaganda which stated that all "anointed" J.W.'s on earth will be evaporated up to heaven before Armageddon starts - in order for them to have a share in the mega-slaughter with Christ.
If it's in the Watchtower, it must be true! (at least for a few months - until a new light says different!)
