"Urgh," Lana complained as she crawled along the drain pipe barely wide enough for her shoulders, "couldn't you have picked the ventilation to crawl in?"
"I could, but that would have made an awful lot of noise." Answered Ray, from behind.
The distinct and pungent stench of years of algae and bacterial growth indicated that the drainage system was poorly tended, compared to the clean and modern police department it served. Footsteps can be heard from above, the police had mobilised to search for them. A rodent ran past, which made Lana shiver as she despised the small, honourless thieves which plagued the poor. Well at least it's not the sewer - she comforted herself.
They crawled for another five minutes in silence and eventually the darkness gave way to a spot of light in front. To ensure they're out of the police station's vicinity, Lana tapped her holo-com to check their current location. After that she looked up and gently pushed the grating away, sliding it to the side. They got out from the hole and into a small deserted street a block away behind the station.
"That went well," Lana said and brushed her hair to the side, which now has slime caught in it.
"Oh yeah," Ray replied, "at least we didn't get shot at."
The two hailed a cheap cab and got back to Lana's house.
