Benedict Ruth is a second year graduate student, working towards his PhD in biology.  He's not entirely sure what led him to make the decisions in his life that have led him to his current position.  Which explains why he's not sure what decision to make next.

Dr. Simone Mann has conducted groundbreaking research in cellular reproduction that has revolutionized modern biology.  She received tenure about ten years ago.  None of her colleages know what she has been working since.

Benedict is the only student Dr. Mann has advised in the last ten years.

Vonnie The LengerichVonnie the lengerich is one of the species discovered by Dr. Mann.  She initially was brought to the laboratory when she had a bad tooth.  She has yet to be returned to the wild, although she does not seem that bothered about it.
