I have theory

My theory, is that Lena is alive. Yes it is a hopeful theory but hear me out. First we never saw her body, her husband wasn't allowed to have her body or even see her again. Here is the question why did Lena go to her familys when she was so pregnate, was she to hot and needed cooler weather, that has never been mentioned and you would think her Husband would have said something like "I should have done something better to make her comfortable." , but never did.

Lena was brought back home for some reason but heres the thing, she was meant to be the strongest most powerful ever seen. Her Father treated her like a God basically. The only way a woman like that could just die after giving birth would mean she had to be physically weakened and had her powers blocked. I have a feeling her own Father or her Sister or hell both were the cause of her death or dissapearance.

I personally believe that she isn't dead and that she is in a place like the Prince dark world to recover. Remember someone spoke to our baby girl to use her powers, I believe it was her mother. I want them to be happy! I also want her Fahter and sister to burn in hell!
