ABC may be saying goodbye to Private Practice in a few weeks, but viewers will be saying hello to new installments of a few veteran shows and two new dramas.

The network has ordered additional episodes of Grey's Anatomy, Modern Family, Castle and The Middle. This brings the episode totals for Grey's, Modern and Middle to 24, while Castle will air for 23.

Elsewhere, ABC has ordered two more scripts for Last Resort, whose most recent episode improved six percent over the previous one; and 666 Park Avenue, which comes as a surprise because its viewership fell below five million overall viewers last Sunday.
