Indeed, Sir

Yay for the second prompt! I have the ability to write it myself, but I´ve often thought about Mabel´s wedding, and how Bertie and his friends would react to meeting all of Jeeves´ family and hearing him being addressed as "Reginald" or "Reggie" the whole night. Plus, I don´t know why, but I always think of Jeeves´ sister as a widow. So uncle Reggie would give Mabel away, and it´s very possible that Bertie was Biffy´s best man... The situation slashes itself.
