Looking at the man in Black, the enemy didn't know if this assassin was with King Sirius or not.
If he was really one of Sirius' men, then why did he not show himself all this while?
They had been battling and chasing Sirius for 3 and a half months.
So why didn't he show up within that time frame?
Why wait now?
Also... they didn't want to anger any secret organizations in Arcadina too.
If this man was a high-level assassin, he might also have his men hiding around the place too.
Hence they had to confirm his motive before they took action.
If he was a passerby, then by means.... they would let him pass.
Even Sirius and Astar wanted to know why this man had stood on their side too.
They had never planned or arranged for any help here in Arcadina.
So why would he help them right now?
What was his motive?
