I'm trying to picture the scene inside, like I was trying to picture the scene in the tree.

I imagine that some lab-grown 29-year-old from Woking with a mind honed to identify individuals who fit the profile of Real Londoner (as conceived of by 50 opinion-polled racist builders and their wives in the Midlands) picks a stubborn local who can still somehow afford to live here and passes him along to some creative studio.
