String of Declaratives + Anaphora : Finally, even her mental resistance has finally gone, signalling the end of her story -- mind and body has been both subjected to Gilead.

The string of declaratives and the fact that the repetition of the anaphora "I'll" is a final show of power. She is showing her active will of submission -- not that she is forced to submit but that she is, on her own will, submitting. In this way it is not only a show of power but a transformation of Offred's fiestyness with Moira in her to her most submissive self, becoming finally a true believer.

Contrast to the peacefulness and acceptance of her visits at the wall, in which she does not distract herself from the figures. It seems she has finally snapped, finally decided she is sick of all that goes on -- which signifies an ending to this story.

She is aware what she is doing is out of place and her realism is gone. She is a lot less realistic without Moira.

She is different now, she is less composed, less cautious -- Does this have anything to do with Moira gone? Her wisdom is gone?

Does this mark some end of her, some change? Because Moira has such a big influence on her driving force, and now Moira is changed? Also, because Moira "must know some of what I'm thinking", without her saying it, she is acting as a foil, a double, a twin spirit

Knock to reality just as in her mind -- Offred is a generally much more confused mind who constructs her own story and lives in the past -- but Moira serves always as a wake-up call
