Burton being a model, which is his other job, the one Iris got him with one of her designer friends.
The top one didn't have much of a direction, we were just talking about silk shirts and tight silver jeans, but the other one was because Joey - who plays this designer, Sigrid Amsel - was talking about an Urban Warfare line, and that got me thinking about all those holster bags and helmet-looking hoodies you see sometimes on Tumblr. And then I realised that Burton is pretty, but very small and skinny, if he's going to be in an Urban Warfare photoshoot, how, exactly?
So that's how he comes to be the sprightly scout-type character with the staff. Obviously the shoot had other models of different sizes with guns and baseball bats and swords. One of them may even have had a stake.
I may even draw the group shot if I get the time.
