Ash was about to completely lose his mind. They had been staking out the area the werewolves managed to track Ruby's scent to before she disappeared for over a week with little to show for it.
They managed to capture a few Cromwell vampires in an attempt to make it inside the barrier that was no doubt nearby but they had more backbone than Ash's wishy-washy former comrade. Each one of them insisted they would rather die than give up the location of their base. So they did.
These vampires were fairly easy pickings considering how many werewolves there were but they couldn't rely on this method forever. Eventually, Dorian would realize what was going on and refuse to let any of his men leave the safety of the barrier.
"We caught another one!" Reggie, one of the betas, howled with glee.
