[Walter says "seventies" and Bertie thinks 1870s. Except Victorian Regina was still queen then. So Bertie is confused. But Walter also doesn't look 70 years old, so Bertie just chalks it up as one more peculiarity of living on an alien planet.]

A dear friend of mine, Rockmetteller Todd--Rocky--takes much the same view. He's a poet you see, and so is allowed certain allowances in matters of dress. Artistic eccentricity and all that. Only special occasions will entice him out of his pajamas.
