I find it odd that they are friends in the first place. Remember that FMV sequence where Genesis was raving about wanting to be a hero? No sane person would be friends with someone who wants to surpass you in any way possible.
I guess this is the case of "you reap what you sow." Too bad for us that the stupid fans had the majority of the voice. Waaah!! I want Mandy Moore back!! Her voice is so beautiful! So angelic sounding!
