So, he’s got snow boots on, and there’s a small hammer on the dryer. He’s sitting on the washing machine while it washes something he doesn’t want anyone else to see. He’s under stress but he’s controlling it. A day or two ago he suffered an injury to his face, perhaps as a result of an assault.
Conclusion: he’s washing something (likely his coat/jacket) to destroy evidence of a violent crime he’s committed out-of-doors, and he’s armed himself rather pathetically with a small hammer to defend himself against someone who is still a threat to him and knows where to find him. He’s no criminal, but he’s committed a crime and he’s in big trouble.
