Agent Aslan's "i Know Not" is a string of admissions from someone who has been hurt by another person and is trying to make sense of it. Almost every line starts with "i know," which gives the poem a tired, repetitive rhythm, like someone going over the same thoughts again and again in the dark.
The speaker begins by accepting the blame, but the picture gets more complicated. The other person is described as cold-hearted, someone who laughed at the speaker's downfall and hoped for no rescue. Yet the speaker also senses a shift: it is "now my turn," and the other person is watching, afraid of getting burned. The last stanza flips the opening. "It's not your fault" sounds less like forgiveness and more like bitter irony, since this person never asks "why not."
The mood is weary, wounded, and quietly resentful. The speaker seems to know far more than the repeated "i know" lets on, and the title, "i Know Not," hints that all this certainty may be hiding real confusion.
