I obtained Auriel's Bow and completed Touching the Sky, but now Serana won't give me Kindred Judgement. Is there any way to fix this using console commands?

If she won't talk to you and is standing like she's about to fight something (blade in hand, magic out, w.e) and still has her weapons out when yours are away, knock her out and then talk to her.

She's not in a fighting stance.

Do it anyway and try..... knock her out (As quick as you can, so she doesn′t go mad)
