I don't really get the idea of hideout either. Wouldn't anyone who checks property records in Nick's name or tracks his phone or sees his bills just be able to find him?

Yeah, but Rosalee didn't really sign up for it.

Juliette coming back alive as a full-blown villain would be pretty awesome. Not only would she be an extremely powerful foe, she'd also know all of Nick's moves and secrets and she'd have a very personal and potent vendetta against him.

"I feel like we are now supposed to think that it was Trubel in the
locked room making the horrific noises even though that doesn't quite
seem possible."

Its not about being good mothers, but about being good people in general.

Do they have to explain every act of violence or just murders?

Adalind as an independent career woman would've actually been more interesting.

Because she's not doing much atoning. So far, she hasn't even taken responsibility for her actions. She just walked into their life, expecting Nick to protect her because of the baby and others to support her in this new life she now suddenly wants.

That's funny - because Adalind has pretty much played variations on the role of manipulative bitch for four seasons now and Juliette went from clueless girlfriend to amnesiac to normal again to an angry Hexenbiest. The showrunners like Claire Coffee and that's why they've kept her around.

"she has a thing of latching onto a male protector and trying to be what she thinks he wants her to be."

The only one who wanted her dead was Juliette and Juliette's gone. The Royals don't care about her and everyone else is bending over backwards trying to accommodate her. She's really not in any danger right now.

"…while a romantic pairing between the two feels inevitable it doesn’t feel unwelcome at this stage."

Or maybe she was in there with the growling creature and that's how she got those bruises.

I'm not buying the whole "she was under Hexenbiest influence" stuff. Adalind had lost her powers before and during that depowered time, she chose to sell her baby.

Actually, Spike had to go a long way even before he came back with a soul. And their "relationship" in season 6 was portrayed pretty well - it was toxic and destructive.

Or the fact that she put Juliette in a Coma.
Or that she tried to kill Aunt Marie.

With a Samaritan agent beside her.

Its entirely possible that Finch had built something like a personality matrix - after all, the whole idea of building a machine came from trying to make something to think for his father. On the other hand, Finch may have hard-coded certain "values" right into the core and written the rest of the algorithm to stop…

Not if a hundred other crime-lords were killed the same night.

She might if Finch coded her morals into the core heuristics - which does sound like a very Finch thing to do.
