I don't understand this Royal Bloodline to begin with. Aren't all subjects of Ymir descendents from Ymir and King Fritz? Don't all subjects of Ymir have royal blood? It feels like this is all in Ymir's "head", the blood doesn't really matter, even if Uri had a child with some girl, the child's blood wouldn't be any different from anybody elses.

Just saying, it can't be the blood, that just doesn't make sense. It seems to work more like titles, like "only those withing 2 degrees of separation between them and the last king can become the next king", and for some reason Ymir also accepts the division between the Reiss and the Fritz family to count, so, even though Zeke is from a branch that hasn't been King for like 9 "generations" (13 years max), Ymir still considers him to have "royal blood". In the end, it seems that who has royal blood is who ever Ymir thinks they do.

Unfortunally, this doesn't matter much more now, since Eren has made direct contact with Ymir and may have bypassed this royal blood limitation (maybe), but considering how important this was until the Rumbling, I would just to understand better how it works.
