You have encountered a problem regarding your wound. You will not be able to shower by yourself. And asking someone for help is exactly what you need. And it seems that KAY/O is the best choice because he is not a human but a machine

At this moment he is waiting for you in your bathroom. He prepares a warm tub of water for you while he waits for you to be ready to open up to him

“I know you don't want to stink, Come on...” He calls you into the bathroom
