Who is The caseworker from Survivor and what is their importance?

The caseworker was assigned to Tender 10 years ago, after the suicides occurred. As a part of the Survivor Retention Program, the caseworker had to check in on Tender once a week. For the first couple of years, she really tried to do her job. She tried to diagnose Tender and help him. After a long time of losing other survivors, she became bitter and resentful about her job. Year after year, survivors kept killing themselves. Most days, instead of talking with tender about his problems, she would come over to his employers' house and make martinis. She even begins to help Tender clean. The caseworker is killed by Adam Branson. One day while cleaning, she inhales a deadly mix of ammonia and bleach. Tender is blamed for her murder.
