Yes I still agree.
What I also find REALLY wierd is that his first sentence is something like "hurry, in the grass, there's a tadpole like those we have in our heads"...
There are absolutely no reasons for him to say that right at the beginning of the dialog...
I think he says "brain things" and he's referring to an Intellect Devourer.....
Well, I'll check the french translation but it does not change a lot of things... He's not right next to us...
And what if you first enter the ruined temple now that it's possible (not killing the intellect devorer) ? Is he saying something else ?
