Ross decided he wasnt going to stand there and wait for something to happen.  He put some coins on the bar and told the barman not to give him another pint. Instead he walked towards the exit of the tavern, hoping he could find the trail before it got too cold.  He walked outside and sure enough, he was able to catch a glimpse of the woman before she disappeared around the corner and into an alley.  Ross followed slowly and quietly, stopping at the corner and glancing down the alley.  He could see the pair at the very end.
