Wow, so much Flemeth "hate". I never viewed Flemeth as a bad mom. I even thought Morrigan and Flemeth had a somewhat decent relationship. Like when she first comes along with you in Origins, Morrigan tells her mom to not forget the pot on the stove or something like that because she would hate to return to a burned down hut. Then Flemeth says it's more likely that Morrigan return to find the hut and all of the Korcari Wilds swallowed up by the Blight, then Morrigan stutters on her next sentence with a sad expression, as though she didn't mean to offend her mom, she was just making a quip. The banter between Flemeth and Morrigan always seemed very playful, even I sometimes joke around with my mother in such a way. The only time I noticed animosity between them is when Morrigan found out about the body swapping, then she wanted Flemeth dead, which is understandable, even if she is your mother. Plus, Morrigan always talked about how she wanted to leave the Wilds and travel out into human lands, iirc, she just never felt ready. She multiple times even ventured into villages but always wound up going back to the Wilds under Flemeth's thumb. She could've left whenever she wanted, but she didn't. I don't necessarily think Flemeth is a bad mom either. We have no idea how their actual relationship was, besides the banter between them at the beginning of Origins, which again to me, seemed more playful, and less hostile. I think it was a bad idea for her to raise Morrigan all alone in the Wilds with no friends, yes, but it all seemed to be for a greater purpose that Morrigan would hopefully, eventually come to appreciate, even if she didn't completely understand her mom's motivations at the time. Then again, like I said, if Flemeth was really that bad of a mom, Morrigan could've left at any time, like she had done multiple times in the past.
I didn't really understand the Fade scene in DAI. Morrigan says she'll never be the mom that Flemeth was to her, and I was just thinking "well what kind of mother was she?" I had nothing to relate Flemeth's parenting skills to because I didn't know her parenting skills. I still liked the scene though, if only because of Flemeth's reaction. Any woman would be distraught over such an accusation, especially coming from your own child. I felt more connected to, and sympathy for Flemeth, than I did Morrigan. And now, after having seen the end, and heard the rumors about Flemythal wanting to give godhood to Morrigan, I now feel even more pain. She wanted the best for her daughter and got misunderstood and shunned for it, albeit that was partly her fault. I suppose she couldn't tell Morrigan the truth because reasons, the same excuse the Grey Wardens use lol. And look where it got both of them...
Anyway, I don't think Morrigan will ponder over Flemeth's death for long. She seemed pretty sad that she was now a slave to her mother, but once/if she finds out Flemythal is dead, I bet she will be surprised, then a little sad, but then overall relieved, in that order, that she doesn't have to worry about Flemeth popping back up into her life, and trying to take control of it again. She might also be a little sad she missed out on that godhood business, but ultimately get over it relatively quickly.
