RICHARD: Linny Lott.
EMILY: That mouse?
Richard’s ex is called “Linny Lott” in this episode. Later she is called Pennilynn Lott. Linny sounds like a reasonable nickname for Pennilynn, but mysteriously, she is never again referred to as “Linny”.
Emily criticises Linny as too meek and mousy, with a rambling, discursive style of speech. Later, Richard’s mother has a quite different assessment of her, and this does not seem like a very good description of the woman we later meet.
