Shawn listened hard as Jack appeared at the opposite end of the alley. He watched the shadows carefully, inching forwards. These things were stealthy as hell...
"Rrrgh, ghrrh," Shawn muttered, but loudly enough for the noises to travel down the hallway. He continued to growl, trying to replicate the noises he had hear Janet make when Jack had taken him down to the vaults. Perhaps this would draw the alien out-it all depended on whether or not he was actually doing it right.
