Briony addresses the issue of her false ending in the very last passage of the novel, “I like to think that it isn’t weakness or evasion, but a final act of kindness, a stand against oblivion and despair, to let my lovers live and to unite them at the end. I gave them happiness, but I was not so self-serving as to let them forgive me” (351). In her novel, she gave Robbie and Cecilia the happy-ending they weren’t able to have in life, however, even in this fictional account, Briony would not have her characters forgive her and give her the atonement she so desperately needs.
Us, as readers of McEwan's novel, get the "true" version of the story. However, the readers of Briony's novel only get her version. I wonder how her readers will take this ending. It's not entirely satisfying, however, it's much happier than McEwan's ending. Would her readers ever find out the "true" story? In the movie Briony does a TV interview in which she states the truth, however, in the novel there is nothing like this. It is possible that her readers, if they were so inclined, could research Robbie and Cecilia, perhaps finding their letters on display in the museum. This would take a lot of effort, however, so it is possible that the readers would simply assume that the two lovers had lived, together, in happiness. In addition, would Briony's family have gone on believing that Robbie was a maniacal rapist? What about his mother? In her heart she would have known that Robbie was innocent, but is it right for Briony to let her go through her life with her son's name disgraced, even after his untimely hero's death on the beach on the final day of evacuation?
I will admit that I do agree with Briony in that this fictional, romanticized version of the story is a lot more palatable than McEwan’s realistic, though heartbreakingly tragic one. It is so much easier to pretend that Robbie lived through that very last night at Bray Dunes, boarded the ships, and made it back to a waiting Cecilia in time for the final scene of Briony’s novel - finally being able to have the time together they so yearned for and so deserved. It’s not true, but it’s much easier to accept than reality.
