Again the collision of forces inside his brain.
Of course if there was a way out of Hell, the Church wouldn't tell him.
Mid-level generalizations prevent that.
The vocalization 'The Church wouldn't lie to us like that' is generated, and then struck from consideration because what if Merin can figure it out (deeper desire, blocked overtly, continues to exert pressure of rationalization): obviously Merrin would not believe that, obviously, what with it being blatantly false, so he shouldn't say that and lose her trust (the deeper desire is happy with this conclusion and does not permit further reasoning about whether Merrin would in fact not believe it or if there are things he could say to make her believe it)
(...And wouldn't it have been nice if he could get Mariona like, 20% this 'ambitious', and not any more ambitious than that.)
The question of whether Mariona could have been like this if she liked her job doesn't promise good things to any level of him and is therefore dropped from processing.
