This might have been discussed before, but based on the reveals in the last 2 - 3 episodes, I think that the general direction of the series is:

When Juliette became a hexenbiest, it drove her insane (or changed her brain chemistry enough to create insanity). The HW treatments suppressed it behind the Eve persona, but the exposure to the Splinter "cured" the condition.

So so, but needs a little more humor.

Why do I think that with the Magnum, P.I. teaser from earlier this year that the real Archer was actually in Hawaii the entire time living his fantasy, with a Krieger-bot taking his place ln Los Angeles?

I don't like "were-Wu" as Wu is effectively woging into a more primitive human form, not something more animalistic like a typical Wesen. And as he learns to control it, IMO, he's becoming Grimm's version of The Hulk.

The virus probably reactivates old DNA. In a Blutbad, this creates a more primitive form somehow tied to lunar cycles, while in succeptible humans, it triggers Neanderthal DNA in "fight or flight" situations, when under stress or in pain (cut by the broken jar,) or possibly when the mind is in a dream state.

The crazy guy on the boat is probably still in the Atlantic off the East Coast. Even if he thought that Mike was on the West Coast and wanted to get there, it would take several months to sail around Cape Horn at the southern tip of South America then back up the west coast to Malibu. It's also a dangerous route…

The moment Liza realized she needed his signature on another form, I knew that another shoe would drop, and once she headed towards the barn, I said to nobody in particular, "It's a sheep".

I could swear that when the lights first went out and the characters moved into the great room, you could see the burners going in the background. Then in later scenes, I think we're supposed to assume that they turned them off.

I think you're looking at a situation that can be analyzed in light of something Adalind said a few episodes back about wondering how she and Nick would interrelate if her hexenbiest powers were no longer supressed. Adalind is a much different person now, maybe in some ways similar to Juliette before she became a HB.

Old enough to have seen Hot Dog: The Movie on VHS in 1985, or so, and after the initial ski montage — where I also expected them all to fall — once they moved into the lodge, I realized that it was a parody of the '80s films.

I recognized the mountains as the Sierra Nevada, but didn't see Tahoe in the background of the shot from the top of the peak, so figured it was Mammoth Mountain Ski Area in the Southern Sierra (I skied there for a week in 1979). The trail names on one of the signs, "Unbound" and "Broadway" check out with MM.

Turned out the only thing I liked about the show was the appearance of the blue 1973 - 1974 BMW 2002 as the "love car" in the first act.
