So not only is Jack safe, but there is time yet for the kerfuffle in the Magic Kingdom to go down, and time yet for Parson to make it through the portal. It's not Gobwin Knob's turn, so they can't claim the city, and there are still enemies in the battle space. If they managed to kill Slately, the side would end and everyone would be a barbarian (thus, no capital and no portal). If you'll remember, Gobwin Knob kept its portal even after being completely destroyed at the end of book one, and it did so because it was still a capital city even if it didn't have two stones resting atop one another.
So, Jack could leap through the portal and join the coming fray in the MK, leaving (after the second blast) Wanda and her Deadite minions sitting on a perfectly good capital site, with Jack, Parson, Sizemore & Friends in the MK with a tunnel that leads back to GK. A quick distraction from Jack (who's very good at such things, and the whole gang has time to race down the tunnel, jump through the portal and leave GK with a massive advantage in casters.
