Kate Walsh — Addison Forbes Montgomery
What it means to hit 100: "It's funny because last season, I thought we'd hit it, but we stopped at 22 episodes, so I forgot about it until we were at the table read. I was like, 'Holy crap, OK!' It's amazing. It's only because the fans that we got to 100. Yes, it starts in Shonda [Rhimes'] endless creative mind, and the network support, but they support it when the fans are in it. This is as much a celebration of our fans."
Favorite episode — "The Hard Part": "I really love the car-crash episode, when Sam and Addison got stuck hiking. I loved that one because it felt like an action movie within our episode."
