As a working artist, there was nothing remotely realistic about how Grillo acted. It al rang incredibly false. And BTW, when artist get together they talk about art.
And who was that guy who looked like Axe at the end. Some rival makes an obvious and petulant insult and Axe is suddenly insecure about who he is and where he came from. Utter BS. Axe doesnt back down or feel inferior to anyone.
Really poor episode.
