While Stefan apologized with pure remorse and a display of regret, the expression of the two other guilty members were merely husks of sincerity.
And for good reason.
For Beruel, it wasn't in his place to seriously interfere with the enemies, considering it wasn't even within his territory. He simply cautioned himself and decided not to act rashly.
"My original body was searching for the Arcanas as I was instructed to, and I met no resistance. While it is unfortunate that I failed to retrieve any, it wasn't due to any fault of mine."
As a result, he saw no reason to profusely apologize. Instead, he offered his genuine regrets for not taking his enemies more seriously… though there was a limit he could achieve with clones.
As for Legris Damien—
"I would have killed them and retrieved the Arcanas if you didn't call me back. I know I was taking longer than needed, but… victory was within my grasp."
—He sounded more unapologetic than anyone else.
