Lara and Luca are trying to get more information about Bianciardi and about the girl who suffers from memory loss. On a romantic level, Lara isn't making things easy for Luca! It is interesting to notice that in Italian, the terms "Dottore" (abbr. Dott.) and Dottoressa (abbr. Dott.ssa) can also be used for people who have undergraduate degrees or no degree at all. They are used as a formal and obsequious title. It is difficult to find an equivalent in English and many people simplify the title by using Ms./Mrs./Miss. or using no term at all.
