who is father ferdinand
Ferdinand does indeed fall in love with Prospero's daughter Miranda, aided by the magic of Ariel. Prospero does also have a plan for Ferdinand, which is for him to marry his daughter and cement the reconciliation between Prospero, right Duke of Milan and Alonso, Ferdinand's father and King of Milan. It is interesting to note that Ferdinand is presented as more passive than his romantic counterpart, Miranda.
At the end of the play, Ferdinand's role as a key figure in the reconciliation of the shipwrecked royals with Prospero and Miranda is clear. Ferdinand is reunited with his lost fellows and father, and Prospero is reunited with the shipwrecked royals.
