Quote #10

I gave them happiness, but I was not so self-serving as to let them forgive me. Not quite, not yet. If I had the power to conjure them at my birthday celebration…Robbie and Cecilia, still alive, still in love, sitting side by side in the library, smiling at The Trials of Arabella? It's not impossible. (4.47)

The "not yet" here echoes the "not yet" in the scene where Briony apologizes to Cecilia and Robbie. It's not clear, though, what future time Briony is looking towards. When are they going to forgive her? Is she hoping for forgiveness after death? Or maybe she's just not willing to admit it's all over?
