Good to see Merlin's Reaper back. The Harry you've envisioned still has the ability to make the tough choices. Now the question becomes, who is the more powerful mage? The more powerful one survives the bio-weapon (with his or her magic intact?) So the winner will be -- Harry's unborn child!
He or she will be the only magical human left.
In the land of the blind, a one-eyed man is king. . .
Write on, write on!
- I think I'll be able to finish it with a minimum of delay
- It might well be a tie... And of course the bio weapon might not work at all outside the lab...
