You maybe right but I question whether Renard is half-Hexenbeist or half some other Wesen. In fact, I wonder whether a Hexenbeist exists as an actual seperate entity or one becomes a Hexenbeist by injesting some potion. We've seen Adelind "cured" of her Hexenbeist "tendencies" with a drop of Grimm blood resulting in Renard professing "she is now just a girl." So indeed Renard may be showing signs of becoming a Hexenbeist (Hexenbastard? the male eqivilent?) due to injesting the potion Catherine gave him. We still have no definite proof what he is only that it was mentioned he is half human.

History has proven royalty always has affairs with their subjects. Eric looked like he was possibly having one with the girl beside him in bed as he took Renard's call, so I strongly believe the problem Renard had with the Royals goes far beyond than just some affair.

I base my speculations on what I consider canon. That is what is actually shown and said in the final broadcast. If something is refered to I may look into the mythology or history of that reference. I don't look to the NBC webpage or any comments or interviews with the producers, writers, directors, and especially the actors. What they all say may or may not be true either accidentally or on purpose and then the final plotline can be changed. I learned a long time ago with the series Lost not to believe even the creators. So end of story? Not even close.
