In Pandora Hears, Gilbert is Oz’s best friend and loyal servant. Oz is his most important person, for whom he is willing to sacrifice anything; this protectiveness is compounded by the fact that he was brainwashed by Miranda Barma to protect Jack Vessalius (and therefore Oz, who is his medium) even if it means killing. When Gil is drunk, he reverts to his fourteen-year-old self, an insecure crybaby. He cares deeply about the hat that Ada gave him. He is a great cook, terrified of cats, unable to quit smoking in eight attempts, and constantly afraid that as Oz grows, he will be left behind.
Gil is shown to have become close to Alice, despite his constant arguing with her. Though he wanted to kill Alice, but then saved her in the next chapter. According to chapter 65, Gil was Glen’s servant 100 years ago in order to fulfill his duty of being the next Glen after Oswald, and he is also a Baskerville, due to his ability to be greatly wounded, but not killed. He was nearly killed by Jack, in order to save him, his brother Vincent opened a path to the Abyss.He was taken in as a servant by the current Vessalius family fifteen years ago, after he was discovered injured and amnesiac in the Vessalius gardens. He came to be Oz’s closest friend, and was invited to be a part of the boy’s coming-of-age ceremony. During the ceremony, Zwei uses her chain Doldum to control his body and forces him to attack Oz. After he regains consciousness, he recognizes one of the Baskervilles as Oz’s father and when Oz attacks the man with a sword, Gilbert takes the wound and falls unconscious.
I think the most sparkling character of Gil is his loyalty to Oz, even during his time in the Abyss he still remains loyal to Oz. In the black coat and cool hair style, Gil is very handsome, as he lives for Oz all his life, sometimes he seems very melancholy.
