Sadly, Robert's mask was destroyed before he arrived in the city; that said, I suddenly have the burning need for him to talk about it with Crane, perhaps even sketching/showing an image...

...and for Crane to find a way to get copy/make that mask and give it to him. The symbolism and implied message there would be amazing, at least to Robert, because he's currently on the fence over how 'right' his actions were- he doesn't see them as fully wrong, but there's still some problems in sorting them all out.

The unspoken support there would have a huge impact on him.

Y'know.
