A deaf prisoner and member of gang 104. Because of his hearing impairment, Senka is largely isolated from the group and doesn't communicate much. What the gang does know of his story, his adventures in battle, escapes from the Nazi’s and the brutality he has experienced at the hands of his captors inspires a sense of intrigue from the other gang members. Senka’s hearing impairment and isolation within the group depicts the way in which Zeks struggle to know each other on a deep interpersonal level. Even though other prisoners would like to know more about him, they are unable to learn about him because of his impairment.
