What if Harry left Susan to face Mavra? What would Michael do? Would Harry leave both?

What if Harry tells Susan to face Mavra if she thinks she can, but tells Michael that they will intervene if it goes wrong. The next thing that happened is that they are called into the ceremony, Susan goes in with Mavra. Harry and Michael go in separately. The story plase out the same, but Susan can't control the hunger because you left me. Harry dies quick(poison fatigue) and briefly like before but escapes with blood loss instead. Susan dies a full vampire, or lives? Does Susen make Harry a half vampire?

Harry stops the fairy war, but is doing thrall(lives) research instead or ghost(died) or vampire(himself). He knows evil Bob and has him in a separate sabertooth skull. Harry accepts Nick's offer, but gives the coin to Michael. Harry removes Lash into evil Bob. Harry stops the hallow. Summons Lash to escape White Knight. Changes? Does he have a kid with Murphy? Is he dating Molly? Do the Reds try to use Harry on the altar?
