I really enjoyed this episode. Mostly because we end up with more backstory about Capt. Renard which i'm particularly happy about because of the whole 'Royal' thing. Seeing Adalind join forces with his brother also made me rub my hands in anticipation of where that would go next.
Seeing the kid with the double wesen natures did make me wonder about hybrids. When two different wesen produce a kid how does that work? I'm really hoping that this will be addressed in the future especially since we know that wesen don't normally approve of mixed couples and Capt. Renard is half-hexenbiest.
Seeing Hank get judgey at Nick for his ancestors and then for him beating up what to him looked like a kid was a great way to show how utterly violent and out of left field Grimms can appear to regular humans.
Monroe was hilarious, and him questioning Capt. Renard about his condition had me in stitches.
