Every other sense reports to the thalamus before reaching consciousness. Scent alone walks straight into the limbic system — one synapse from the amygdala, two from the hippocampus. You do not remember a smell. A smell remembers you.

This is why the house builds fragrances as scenes rather than accords: a chapel in Seville, a night garden, salt on warm skin. Wear one long enough and the scene becomes yours.
