The first signs of Gene's loathing of his best friend is found when Phineas is caught wearing the school's tie as a belt when having tea with the current Headmaster. "This time, he wasn't going to get away with it. I could feel myself becoming unexpectedly excited at that.He had gotten away with everything. I felt a sudden stab of disappointment." (Knowles 20-21) .
If Gene were a true friend, he would not have wanted for his pal to get in trouble nor be dissatisfied when Phineas did not. Then later on, as Phineas saves Gene from falling of the tree, rather than feeling grateful for being rescued, Gene blames Phineas for even being there in the first place. "Yes, he had practically saved my life. He had also practically lost it for me. I wouldn't have been on that damn limb except for him.I didn't need to feel any tremendous rush of gratitude toward Phineas." (Knowles 25) Gene is also becomes to be quite paranoid, deluding himself into thinking that Phineas is jealous of Gene's academic excellence, and is deliberately using blitzball and the Super Suicide Society in order to distract Gene from his studies. "Finny had deliberately set out to wreck my studies. It was all cold trickery, it was all calculated, it was enmity." (Knowles 45) However, when Gene discovered that his suspicions of Phineas were fictitious, his vile emotions of animosity and disgust only heightened, ".but my understanding which was menaced. He had never been jealous of me for a second. Now I knew that there never was and never could have been any rivalry between us. I was not of the same quality as he. I couldn't stand this." (Knowles 51). .
Phineas' fall from the tree symbolizes a repercussion of Gene's corrupt side lashing out. Gene's hostility towards Phineas is rooted with Gene's own frustration with himself. He compares himself with Phineas and sees that while he has to deal with his own negativity and adversity, Phineas apparently had none to fuss about.
