Hell - City of Demons
And so something begins that Dave will most likely deny remembering.
First he commands the burley demons and the skeletons to call back to Clarissa's current location, right outside the fleshy wall to act as a last defense against the angels.
Next, he commands the spidery ones to hide in the nooks and crannies of the hospital and to infect any angels that look like commanding officers.
After that he sends the worms out(if they are big) to dogfight it up outside of the hospital.
If they aren't big then he has them stick to the windows, firing projectiles if they do that sort of thing and if they don't then they're called back with the skeletons and burley demons.
Finally, he begins the creation of a new demon.
Specifically, fast but deadly ninja demons, bound with the soul of his fallen ninja friends. He knows they went to Hell and they can sure as hell help.
And once they complete he sends them to hide in the shadows of the hospital, being stealthy like true ninjas so that if the angels get in, they'll find the place apparently deserted.
And then, he finally parts the fleshy walls after giving Clarissa a kiss.
"Get better."
And then he leaves the hospital and surveys the situation.
