Grey’s McSpinoff audience

America tuned in for the 2 hour Grey’s Anatomy episode which serves as a springboard for Kate Walsh’s yet-to-be titled spinoff.

21 million viewers tuned in, which is little more than its 19 million season average.

“Addison” has previously been said to travel to the Oceanside Wellness Clinic in Los Angeles, taking a leave of absence from Seattle Grace.

There are two more eps in the current American season, which is still about over three months away in Australia.

The spin-off has the working title of Private Practice.

In the episode Addison is said to tell her colleagues to never “Mc” anything.

Thank God!
