After getting the location from Arslan, Ethan didn't hesitate to head toward the bar he had been told about to complete this task he was put on.
He made sure to inform his team that he was moving into the area so he could have some backup with him. However, the backup was limited to Officer Jake and Ava, the only two who knew about this unofficial assignment. They were working off the record, having yet to inform Lieutenant Tasha about the entire operation.
Their plan was to build a solid case against Arslan and his crew, trying to gather as much evidence as they could before involving the higher-ups in their investigation.
They didn't want to repeat the mistake they made with Detective Cain, who looked the other way when it was time to close the case on Arslan, opting instead for the safer route of charging Fat Sean and his people with murders he had nothing to do with.
