King's Dark Tidings discussion

So, I wanted to ask everyone's thoughts on something. In book 3 when the refugees landed on Cael and entered the city, Rez was "tested" when he opened the doors. Apparently he momentarily died and was assisted by the "bug eyed" healer Aelis Cress. I think it this was the incident that marks the spot where Rez stops acting like the Rez we know and love and starts to act a bit more erratically (I am not just referring to his lack of ability to focus, but more on how he seems to start his paranoia and not trusting Tam and others).

Now at the end of the book we learn that Aelis is a demon when he abducted Tieran, Sheila, Frisha and Ilanet.

So I am wondering, do you all think that Aelis did something to Rez to make him this way or do you all think it is Cael and the Shielreyah?

Also, who else thinks Minder Thoran is another Demon?

I think you are right on both counts minder thoran is a demon or possessed by a demon. If he was demon/possessed before he got on the ship I am not too sure but probably yes because I didn't like him much and thought him a bit suspicious.
And yes I think Aelis mucked about with Rez when he was revived at the gateway. What he did I have no idea I will have to think on that.
