DUKE SENIOR Welcome, young man;Thou offer'st fairly to thy brothers' wedding:To one his lands withheld, and to the otherA land itself at large, a potent dukedom. (5.4.8)
As Duke Senior welcomes Jaques de Boys to Orlando and Rosalind's wedding, it becomes clear that marriage saves the day in a play characterized by family treachery. As we know, younger brother Orlando has received the short end of the stick – after his father died, his older brother inherited everything and treated him like garbage. Still, when Orlando gets hitched to Rosalind, his nuptials provide him with a new family and a new fortune. Not only does Orlando get to marry his dream girl, he also gains a father-in-law (Duke Senior) who replaces, to some extent, his own dead father, Rowland de Boys. What's more, Orlando is now the heir to his new father-in-law's dukedom.
