Uh, don't forget that as a Grimm Nick would see Juliette as a Hexenbiest any time she was emotional or aroused, not just when she was fully woged. Henrietta didn't woge at all when she was seducing Nick because she wasn't feeling any real emotions - she was just using her powers to manipulate him. There might come a point where Juliette is able to control her emotions to the extent that she never woged but that will take time.

I'm sure that Juliette had been stewing all day, thinking about Nick not accepting her, stirring up feelings of anger and resentment. By the time he got home she was in the mood for a confrontation and that explains her being so aggressive and mean-spirited. That happens all the time in real relationships, even without the added complication of one of the parties having an inner Hexenbiest influencing their thoughts. :-)
