Riley chewed on her lip for a few seconds trying to formulate a plan real quick. She thought of just shooting them with her rifle but that made too much noise and clickers were on the other side of the wall.
She quickly unholstered her pistol then made sure the safety was on before handing it to the girl. 

”Alright here's the plan take this pistol and climb down the latter then quietly get to the two cars by the runners, ill cover you from here and if things go south you will need a backup plan that's what the pistol is for,” 

Riley took a look around then laid prone setting up her rifle, she wasn't going to fire her rifle unless it was absolutely necessary. ”By the way, my name is Riley.” she gave the girl a small smile and nod before returning to watching the runners eating a fresh kill.
