If you think this has a happy ending, you haven't been paying attention.

The line is a meta-commentary on narrative expectation: it warns the audience not to assume conventional, comforting resolutions. It signals a story-world governed by harsh consequences, moral ambiguity, and the possibility that protagonists can fail or die—an attitude many readers associate with modern “grimdark” fantasy and with the tone of the A Song of Ice and Fire / Game of Thrones franchise. As a quotation, it functions as a corrective to wishful reading, implying that the work’s prior events already demonstrate the pattern: if you’ve been attentive to the established stakes and outcomes, optimism about a tidy happy ending is itself evidence of inattention.
