He seems reluctant to let you go, though it's hard to tell; perhaps because of the hostile realm beyond, perhaps because he so rarely has visitors. He tries to communicate something with his hands - it's a little hard with one arm being so recently stung - but he makes a little triangular steeple with his fingers. "Raphs 'teal me net..." he reminds you; a phrase that tonally seems also to concede and bid you farewell, and you leave the stricken but recovering mutant Olio to his cats.

A few more traversals of building to building and you spot again with your honed senses another of the thief signs. "Ah... We're close, then - we'll light a fire in the chimney here. There will be a bit of treated wood somewhere near it that will have little carved notches in the length; three notches is the one, and that'll burn smoke that'll look green to the right lens. Unless they've changed the signals... but we've got nought but to try." The reinvigorated Cestié is halfway to lowering a knotted rope for your trio to climb down into a window of the building beneath you and find that notched wood, but at that point you spot it - a building across weedy canal from you. Its top floor has collapsed and crushed most of the lower story, and the entire foundation has halfway surrended to the marsh. The end result is that the lower floor is underwater on the east side and above on the west - with a triangular half of a doorway visible at the waterline. You notice also what no one else would do - the faint scrapes where a clawed, ratty hand have grasped that doorframe going in and out over time. It may not be a skaveni that dwells here; any mutant could have such claws... but it might be. That would be a chance to recover Olio's net, which is one thing; and perhaps more compelling, a chance to kill a ratman. Or it might be an unnecessary danger and distraction - but is it worth leaving to the rear of you, when you go?

It looks cramped and dark in there... For most, that would be enough to deter.
