Sam is looking at Arthur and the remaining two. The contents of three recording crystals have already played and the three guests have seen the three battles.
Sam has sent three people to follow them and record the battles if occurred and send it back to him.
And he made this not for the purpose of showing them to Arthur and others, just in case if something happened, Sam would have a specific target to focus on.
He did give them some trump cards so that they can escape in some cases.
Even though the recording crystals didn't capture everything in the battle particularly in Philip's case, they still have the most critical parts.
After showing the three recordings, Sam leaned back and relaxed as he observed the change in the facial expressions of the three 'guests'.
"If the information you have is about these kinds of threats, then you can keep it to yourselves, I have faith in my friends."
