Hades fast-talks Mephisto into doing his dirty work:
*puts friendly arm around Mephisto*
"Hey, Mef -- I can call you 'Mef', right?? Sure I can!! Listen, Mef, love the whole 'marriage wrecker' deal, babe! Got me a Wonder Boy and a traitor needs a quickie divorce, the more misery involved, the better, knowwhatImean?? But, slight snag -- his Aunt tends not to conveniently die, her being immortal and all. I would send the minions to take care of that whole godhood thing, but I'm still torturing them from the last time they botched that particular scheme. You know how it is when you rely on the help, I'm sure." *rolls eyes*
*immediately brightens up again* "But hey, you're better than that, right, Mef?? A real professional!! So I know I can count on you to go out there, and do that thing you do one more time! And hey, feel free to throw in as much physical pain on the happy couple as you see fit! Tell 'em their old pal Hades says 'DIE!!'"
*pushes Mephisto out of Underworld*
