Peaky blinders ep 2

I watched the episode 2. He recapitulate quickly the life of the Shelby family. Thommas try to make monney, and go to see someone who control the game of run horses. We discover that arthur has some psychological troubles because of the war. He is violent, but less cruel tha, thommas. Thommas have a scary look, like he know what the hell is he doing and the consequences but he understand it and use it. He have one fear. We can see him in the middle of the episode, wake up in the night because of a terrible war nightmare. He is in a tunnel, and there is ennemys behind him. He is on he's knees, because the tunnel is to short. He has to go to the exit, but he can't breath. He turned around, saw man's coming after him. And then he woke up, seeing the wall a front of him like the exit of the tunnel. But except that, he have no fear during the day light.
