Cassie O'Donnell is the Head of Communication in Site-29; best friends with Dr. Vincent Minnow. She is caring and often scared for Vincent and his lack of self-preservation. She's 37, very forthcoming, and can argumentative. Acts like a sister to Vincent.

2.

Hopefully it gets fixed sooner or later--Oh! I just realized, I can upgrade all of our computers and help Axel with getting new cameras for the entire site.
