I wonder what goes on in Fay's mind when she sees part of the truth with the wise eyes of a child, an' wantin' to know more, meets with strange falseness from you?
Wait! You are false in a way, though you're the best woman I ever knew.

What I want to say is this.

Fay has taken you're pretendin' to--to care for me for the thing it looks on the face.

An' her little formin' mind asks questions.

An' the answers she gets are different from the looks of things.
