My first thought was that you're imagining things, but I checked and you're half right. Yatul and Bolar are only ever referred to as Aunts. So we can't know for certain either way. Maybe Bethesda did that deliberately to keep Skyrim at '13+' ;-) Ha, ha. Well, here's everything I found out with my Khajiit (I'm working on the unofficial translation to Japanese, so I've got the dialogue noted down). This is what Urog, his daughter, has to say. * My brother keeps trying to spin these fantasies to me about my aunts and our father. He's crazy. * Sometimes I wonder if my aunts are right about my father -- he does seem weak. * Yatul's been teaching me to hunt. I'm still learning, but she's the best teacher I could have. This is what Dushmamub, his son, says. * Haven't you seen how my aunts act with my father? It's beyond strange. * I never knew my mother, but I doubt even she acted as affectionate with my father as Yatul and Bolar do. * My sister is blind. I've told her she shouldn't spend so much time with Yatul, but she won't listen. Thinks she's nice. Chief Mauhulakh himself doesn't have much to say, except to bemoan his lack of wives. * The blessings of the mine have been many, but I have no mate to share them. * Been married many times, but the gods keep taking them from me. Then there's Yatul. * Mauhulakh. He wants to be a leader but spends too much time moping over women. Bolar and I should be all he needs. * Orc chiefs should be strong and stand alone. They need no companions. Progeny is a poor excuse. * I know I sound abrasive. It's just that I love Mauhulakh so much that I want us to be happy together. It gets more confusing with Bolar. * I've read the entrails many times, but can't fathom why Mauhulakh's wives keep finding tragedy. * Urog and Dushnamub were such lovely children. I held them as they watched their mothers die after birth. They know me best, now. * Mauhulakh was such a darling boy. Until he got older and started having opinions. So, either Yatul and Bolar are Mauhulakh's older sisters (or sister-in-laws) or they are actually Mauhulakh's aunts, and Dushmamub and Urog's great-aunts.
