Elsewhere, a paranoid Holden runs a series of diagnostic scans on himself, looking for brain damage and, most crucially, the presence of protomolecule in his system. The tests are negative for both, which is a relief, except what is causing these hallucinations? Speaking of which, Miller returns, complete with private-eye fedora, which Holden can't handle. Miller's words seem to cohere better now, but he's still babbling about old Star Helix stories. Holden eventually gets feed up with the gobbledygook and starts yelling back, which is when Amos shows up to see his friend and captain yelling at an empty room. Amos is actually remarkably cool about it, and Holden promises to tell him if anything is truly amiss.
