"I´am asking you again" she says "give me the gun!".
"Here" he hands Clem his gun. She takes gun from him.
"Is there a way out ?" Clem asks.
"What ?" he looks surprised.
"Street is filled with zombies, I need way out of here" Clem asks.
"Well, you can use roof" he tells you "jump onto another building and down to back alley".
"Thank you for saving me, I´m keeping the gun. If you follow me I´ll shoot you."
Clem walks out of the room, up the stairs, climbs ladder onto roof.
