Regarding Haven – this is an incorrect interpretation of the clue.

Why is that? You know, this is a clue about the serial killer, and since it's the first one, it could very well point to all three of them at once. I don't know how it was with you, but we've already encountered something similar, and it's perfectly normal.

Okay, do as you wish, but I'm voting for Phoenix's execution.
Then we need to take a closer look at Hermit, Deriel, Guru... and Azi :O. One of them is definitely the serial killer, maybe even more than one (this is my advice!)
