When Joshua mentioned two men observing the place, everyone understood it might have been Dan and Vic as Dan was their expert architect who studies the entry and exits of the place and Vic's job was to collect information of all the employees working there, these were their duties so as to plan the perfect attack plan.
These two indeed visited the Vulcano island to confirm the man they were searching for was there or not and they indeed called James to confirm it, at that time they were unaware that they were being eavesdropped on by someone.
Vic and Dan looked guilty as they couldn't hide their motive and were seen through by a local.
"Good job you two" James sarcastically praised them.
The two looked down as they felt ashamed.
"Joshua please continue" James commanded.
