Yes . . . it's funny reading through the books and gradually seeing Bertie incorporate all these little phrases and literary references picked up from Jeeves in previous books. I think by the time The Ties That Bind rolls around Bertie is actually borrowing Jeeves' thesaurus.

As for Jeeves, I think Bertie's influence makes him more human, both in the books and on the show. I think in the very beginning all he wants is an easily manipulated master who doesn't fuss a lot and will wear what he lays out for him. Hearing about the many positions he's had before, he strikes me as a (very properly attired) rolling stone that gathers no moss. Being with Bertie gives him some grounding and some roots.
