TheNCISproducers have a big surprise planned for fans of Pauley Perrette.

We realized we couldnt say goodbye to Abby without ever visiting her apartment, showrunner Frank Cardea tells EW.

The apartment is as unique as Abby is herself.

Adds fellow showrunner George Schenck: Abbys apartment has been 15 seasons in the making.

We knew it needed to be exceptional.

We really wanted to live up to the standards our fans have come to expect.
