"Halloys, do you know the maid in my house?"
After saying goodbye to Alya and continuing his return to Springs, Ronald remembered the scene when he first met Halloys, hence the question.
Halloys, however, simply flashed a smile:
"Don't ask, you'll die."
"This is the advice given by my dear old boss."
"It's precisely because the enigmatic maid in your household is extremely dangerous, that I so decisively invited you to join my caravan that night when I saw you."

Ronald raised an eyebrow:
"So you're completely in the dark?"
Halloys responded directly:
"Anyway, it's your family's maid, she couldn't possibly harm you."
"..."

Recalling the scene he encountered at White Shore Castle that night, Ronald had no doubt that there were many in this world who could recognize his identity, or at least sense something was amiss.
If the Adler family's maid were among them...
