Question about Rhea of Thorolund...

Does the Channeler that waits on the 2nd floor of the church ever kidnap her? I tried to find out but Petrus killed her before I could test it. I swear I've played through this game a few times and this quest line unravels more and more.

I thought it would be cool if the channeler kidnaps her and then you rescue her at Duke's Archives, but I'm starting to get bored of this game and am giving up.
