It's so odd first time around for me I loved season 1, 2, and 3 but now I have mixed feelings. I actually am right in the middle of season 3 with my rewatch, the aforementioned "vault of the heavens" was the last episode I watched. Later in the series Beka becomes the godmother of all the Nietzscheans which I find hilarious..... But time travel. Also plot hole isn't it, if she was their prime matriarch why didn't Tyr or anyone recognize her?
