I think the Authority is searching really hard for Sarah Newlin because she knows something about a cure for Hep V.

"We're looking for Sarah Newlin and heard she may be here. You know her?"
"Ain't gonna lie. Yes, I know her. Biblically, know what I'm saying? hahahaaaa!!"
"Where is she?"
"Ain't telling."

Uh, isn't the "monolith" the new, umm, giant, monolithic computer, not the elevator??
