“Prithee, please.” The archaeologist bids to the butler.

Except, in spite of being set in the appropriate era for cant, “prithee” is not the word of usage. The Suffolk twang that Fiennes uses may sound as such, even if only to avid linguists or word nerds like myself.

However, the enunciation is that of a name. One profoundly familiar, in comparison to an obsolescent synonym for “please”.
