Celia’s glass eye symbolizes both Franklin and Celia’s naivety about Kevin’s violent and nefarious nature. Eva spends years trying to convince Franklin that Kevin wants everyone around him (but particularly Eva) to suffer, but Franklin won’t entertain the idea, defending his son at all costs. Celia turns out to be like Franklin, and she fully trusts Kevin even after he blatantly tortures her. Kevin’s most heinous act before his mass murder is burning Celia’s face with drain cleaner, which destroys one of her eyes (or so Eva suspects). Kevin’s malicious intentions are obvious to Eva, but, to her frustration, the rest of her family seems to ignore these intentions. In turn, Celia’s physical inability to see ultimately parallels her (and Franklin’s) inability to see Kevin for who he is.
The novel closes with Kevin returning Celia’s replacement glass eye to Eva and apologizing for his murders. This is meaningful for Eva, as it’s the only time Kevin has ever owned up for the pain he has caused. In fact, since Franklin and Celia were always ignorant of the truth about Kevin, it’s one of the only instances in which anyone in Eva’s life truly recognizes what Eva has gone through—though it is, of course, sadly ironic that Kevin is the one to acknowledge this.
Celia’s Glass Eye Quotes in We Need to Talk About Kevin
Because after three days short of eighteen years, I can finally announce that I am too exhausted and too confused and too lonely to keep fighting, and if only out of desperation or even laziness I love my son. He has five grim years left to serve in an adult penitentiary, and I cannot vouch for what will walk out the other side. But in the meantime, there is a second bedroom in my serviceable apartment. The bedspread is plain. A copy of Robin Hood lies on the bookshelf. And the sheets are clean.
