When she tapped Isaac on the shoulder and put a finger to her lips, Isaac gave a brisk nod, his breathing heavy because of the adrenaline.  She started to sneak off and Isaac fired another shot off down the stairs before following her, trying to stay as quiet as possible.  The injured raider at the bottom of the stairs fired more shots back, not realising that they were gone.

The girl led him down a different stairwell, descending beyond the groundfloor and to the basement level parking lot.  [i]Perfect.[/i]  As soon as she let go of his hand, Isaac changed his empty gun clip to a fresh one, all the while running after her.  Out of the parking lot and into the dead streets, Isaac followed the route she was taking until he suddenly took the lead.  He looked back to see why she had stopped, then halted himself to watch her go start looting a table for something that'd caught her eye.  Looting at a time like this!

"Really?" he asked breathlessly, once she caught back up.  There was an exasperated smile on his face as they got back on the move.  "Come on."

They ran for another twenty minutes, taking a left turn here, a right corner there.  On his left arm, Isaac wore two wrist-watches.  One of them was like any other watch, it showed the time.  The other was a compass.  He used it to make sure that they were steadily heading south-west and deeper into New York.  After the running, they walked for 5 minutes to catch their breath.  After that, they were jogging.  Isaac had to be sure that no one was following them.

It was late.  Luck was on their side that no animals, bugs or feral ghouls had crossed their path and attacked.  They made a good distance between themselves and the raider town.  Isaac began looking for a good, sturdy building to make camp - they needed to rest soon as the girl was exhausted, her breathing and wheezing sounding like she might collapse at any moment.

"There," Isaac pointed 200 yards down the street to the big townhouse on the corner.  It was three floors tall, its walls looked in tact, and the buildings around it were rubble, so the top floor would have a good view of the surrounding area.  "We can rest up in that townhouse over there."
