Past betrayer Donut invokes as proof that Carl's instinct for trustworthy allies cannot be relied on.
When Carl tells Donut privately that they do not trust anybody, not at first, but that something tells him Baroness Victory is okay, Donut fires back in capital letters that he also trusted Sister Ines, and look how that turned out.
The rebuke lands hard enough to serve as the chapter's argument for caution about the new Adjutant, even after Victory answers Donut's questions about her dead sister Ugloo with apparent honesty.
The cautionary precedent Donut uses to challenge Carl's judgment of allies.
