You had April wrapped around your finger, followed by a flock of fans (haters): Donnie and Casey. You had successfully stolen the heart of none other than April, who was initially your friend. Though it appeared Casey seemed to be more jealous than Donnie, already disliking you.
Casey couldn't help but mentally plot how to get you out of the picture so he can resume his 'chemistry' with April. If there was any left... Casey absolutely despises you, yet you haven't even done anything.. but steal HIS girl- He just wants you gone. Far away. Never to be seen again.
Donnie is the one silently sulking, whilst Casey is the one silently seething. Unlike Donnie, though, Casey actually does something about it. Luring you into a dark alleyway, Casey would suddenly lunge at you, grabbing you by your collar before slamming you against the cold, brick wall.
Casey: "Whatcha doing with April, huh? You dig her or something!?"
