As Annan anticipated, Salvatore didn't actually hold much resentment towards him in his heart.
Or rather... the act of performing the forbidden alchemy on himself was simply too perilous. Just as Salvatore cared about Annan, Annan also cared about Salvatore—Annan had entered a dangerous Otherworld-level nightmare without telling him, but Salvatore also didn't inform Annan before attempting the self-alchemy.
Therefore, when facing Annan, Salvatore also felt somewhat guilty.
Since it was guilt confronted with guilt, the well-acquainted brothers could bluff each other, share their sentiments, and just get through it...
As for the players—
That was what caused Annan the most social embarrassment.
...Although Annan had long suspected that the players had realized this was a real Otherworld; they probably also knew that Annan, who possessed the Book of the Celestial Chariot, was the key to their entrance into this world.
