Genesis really, really, really hated it when Sephiroth got into one of his moods. So what if he did shove Loveless down his throat. It was poetic! And he felt that it accurately described him, Sephiroth, and Angeal. It wasnt even that bad of shoving down, no matter what that silver haired lunatic said.
He, by no means had to burn his favorite copy in a sealed off room so he couldnt rescue it.
That was just too far. Especially with all the execs there the watch him screech at said lunatic to let him in to rescue it.
So, how to get revenge?
Casually walking up to Angeal, Genesis decided that the man who had to deal with a pranking and pubescent teen SOLDIER would know a suitable revenge. All he had to do was get him to spill without knowing that he spilled until the revenge was exacted.
How are Angeal cut him off, not bother
