I am forever grateful for the balanced way Harrow’s psychosis is displayed. She is a rational person. She is able to evaluate data as sharply as anyone else. Maybe even more sharply than anyone else. She just isn’t sure if the data she is evaluating is all accurate. She reads as someone who has long since adjusted to this self-doubt about reality, and possibly as someone who’s intelligence was honed specifically by the process of needing to run every observation through rationality checks. It makes her weird, socially, but it also makes her very good at processing and deduction.
