What if I only recognized Ian Roberts?
Pretending for a second that it was me instead of Anthony:
The only person in the main cast of Company Retreat I recognized is Emily Pendergast, but I feel like if I asked her "has anyone told you you remind them of >!Jonah's Wife/Sister!<from Veep?" and she said "yes I've heard that before" I probably would have bought it and moved on.
The only cast member that I recognized beyond a shadow of a doubt is Ian Roberts. But IDK if I would have called him out in front of everyone. If, during the hike to find Dougie, I had asked him to hang back for a second and asked him privately "hey man, I took classes at UCB, I know who you are" do you think he would have been like "yeah that's me, the Everest guy is a character I'm working on and I'm trying it out at different company retreats, can you keep it quiet for me?" I feel like that maybe would have worked on me.
