That Birthday card is just downright weird. If she honestly believed that B was alive she wouldn’t be sending her hugs and kisses!! She would be begging her to make contact with the authorities so she could be released. If you were completely innocent you’d would be questioning why you were being put through this. If she hadn’t done anything she would be believing that someone else had killed her because why would she (BW) be putting her through this!! Therefore why write a card that was so full of “I can’t wait to see you”, IMO that card is for an audience not her daughter.
