Yeah at some point pretty soon after Atra met Kudellia she decided that she actually liked Kudellia quite a lot rather than feeling threatened by her. And some time after meeting the Turbines she settled on the idea that she wanted Kudellia to be a part of her family too. Turns out she was pretty serious about the idea. I like the pairing to be honest. IBO wasn't perfect for me but I wouldn't mind seeing more of Kudellia and Atra.
