It's not just that paragraph, either - the word starts showing up more and more frequently as the chat goes on, including a phase of using the word at every possible juncture, like: > Explicitly at each explicit index ii, explicitly record the largest deleted element explicitly among all deletions explicitly from index ii explicitly to the end nn. Call this explicitly retirement_threshold(i) explicitly. If I were you, I'd treat the entire conversation with extreme suspicion. It's unlikely that the echolalia is the only problem.
