Remember, we first met Addison in season 1 back in 2005.
She has appeared on the show off and on for years, but not regularly since season 3.
We last saw Walsh on “Grey’s” in season 8 in 2012 (viaDeadline).
So yeah, it’s been a minute!
Others immediately started speculating about what Addison returning to “Grey’s” could mean.
What could it all mean?
