Ah, alright. tbh, if that was changed, then BW might've retconned it. Well, that's what I'd assume, anyway.
But yeah, let's get back to Flemeth. I can't help but think about what Morrigan says in Witch Hunt, saying that she thought that Flemeth was trying to retain her immortality at first, but now she knows that that wasn't the case. She tells the Warden/Warden-Commander that Flemeth is a bigger threat than they could have ever realized (I'm paraphrasing here, just to be clear). imo, her saying that is foreshadowing what Flemeth plans to do in DA:I. I mean, BW has been working on DA:I since before DA:O's launch, so I wouldn't be surprised if they had foreshadowing in one of the DLCs for DA:I. I mean, if you think back to ME1, there is some, albeit minor, foreshadowing towards ME3, so it wouldn't be surprising that BW decided to have some DA:I foreshadowing all the way back in DA:O.
Plus, if you combine it with Sandal's prophecy in DA2 and the Enemy of Thedas trailer, I'm thinking that either 1) Flemeth is working in collaboration with the Elder One (assuming he's the main antagonist), or 2) she might've had something to do with the Elder One's appearance. Also, if you think back to some of the other stuff Sandal says in DA2, he mentions that there's an old woman appearing at the foot of his bed that she has a 'scary laugh'. I think that this woman is Flemeth. tbh, it wouldn't surprise me, considering how she saved the Warden and Alistair in DA:O so that one of them could preform the DR with her, then saved Hawke and his/her family 'supposedly' to be able to escape being killed by the Warden, even if the Warden took her deal. In the Warden's case, it could just be her planning ahead, but then, she DOES say that she was expecting the Warden and company to show up in the Wilds looking for the Warden treaties as well as saying that she expected Morrigan to convince the Warden to try to kill her, though the latter could just be Flemeth knowing Morrigan very well. She also seemed to know ahead of time that Hawke was going to gain a lot of influence and power and be key to the Qunari problem in Act II and the beginning of the Mage/Templar war in Act III. Whether or not she planned this for other reasons, I can't tell.
