What it means to hit 100: "It's pretty exciting. It doesn't happen very often. It is such a rare thing, especially now."
Favorite episode — "Who We Are": "I like Amelia's episode where she was freaking out while we were doing the intervention. I think that was my favorite. Caterina was so good in that."
