Sejuani's bio mentions how her mother, Kalkia, left the Winter's Claw to run off with a man she fell in love with, leaving Sejuani in the care of her cruel grandmother.
Udyr's bio talks about how, after showing off his spiritual abilities in an explosion of power, all the Winter's Claw members abandoned him except for one woman. The relationship between Udyr and the woman isn't explicitly stated to be romantic, but can we get any confirmation to who this is? Is it Kalikia? Sejuani? Someone completely different?
