Color me confused. Alf did not try to dispell the illusion a second time, instead Derren and Alf were getting ready to enter the building. Granted, they may have eventually gotten around to taking the spell down, but there seems to be a jump there? That said, I'll roll with it
Alf looks at the dark and foul smelling hole. "You know, I think I know what to do with places like that: not go down them. At least, not without a troll in full military armor, carrying a mini-gun, to lead the way. But I guess that doesn't mean I can't take an astral look see. I don't know how well you could talk to your drones down there, but might be worth it to try, for the ability to record? But no matter what we see, I'm suddenly feeling guilty for not checking out the clinic, I think they are expecting us?" His final sentence is said in a tone of self-mockery for his lack of bravery, but by his nervous tugging at his collar it is clear that his nervousness about the hole is real.
He adds "Now might be a good time to remind you that I'm better at supporting heroes and patching them up than I am at being[/b] the hero!"
