"Hmm, I guess. Feels better to be actually doing something."

Nod.

They look, but nothing seems promising.

What's in that floor even?

Jail cells! An infirmary! Bathrooms! 

It's an abandoned prison, that's all.

...right okay.

The vault might be underground somewhere? They should explore other floors.

"There's still upstairs, but underground is a safer bet for a vault. Let's stick together, do a quick sweep of the upper floors, and then try to find our way down."

"Good idea."

No sign of a vault upstairs, either. 

And finding a lower level proves difficult. 

"It would be nice if we had the goes-through-solid-objects Object."

"Don't you have that Object?"

"I do in fact have that object but it's only one-way."

"Does it let you see through things too, or just travel?"

"Just travel. And it has a thickness limit."

"I'll step outside, see if I can find a way down. You try playing with the key some more."

"Okay."

He does.

It's not very productive, since he doesn't have any new information. 

"So are we just supposed to go back, when this doesn't work?"

"I guess so."

"We'll find it."

She returns, eventually. 

She shakes her head.

"...are we sure this is the place?"

"Darwin can get you in touch with our source."

"Who is it?"

"The owner of the comb. He's...hard to talk to, but I manage."

"How did he know about here?"

"His mother was one of the Collectors."
