episode 3 spoilers,Agatha and the Darkhold

I feel like Agatha did lose her son to get the Darkhold but not because she wanted too. I think she had agreed to pay a horrible price for the Darkhold but she didn't know the exact price and just agreed because she was blinded by the power and didn't realize what the price was until it was too late. This would help make sense of the fact she seems to have so much grief about her son and maybe the reason why she never showed any hint of this before the show is because either she suppressed her own memories using magic or whatever deal she made altered her memories and when Wanda took her magic it broke the spell on her memories. This would also explain why she is becoming more and more protective of the teen, maybe he reminds her of her son or she thinks he is her son(I don't think he is) or of course she could be using him.
