I read with her twice. She said something in the very first reading which has incredibly come true and no way a lucky guess. It was something very specific and honestly quite unexpected.
That said, in the second reading we talked about other things, NOT connected to previous conversation. I only asked her if she remembered something from previous reading not because I needed further details on what I asked the first time, but to validate something she had told me. Then I changed topic with her, so even if she was checking the chat she wouldn't "find" any hint to cling to. That's it. I don't need to justify myself with you, sorry. Then if she's a scammer, she's a good scammer. Chapeau.
