Mrs. Byrne is an elderly teacher in Finnegan High School. She teaches history and leads the science club. People believe she has lived more than the average age because she is more into hard, formal words, and has said things about interacting with old historical figures. She is also considered ' kooky ' , like when she and Echo was trapped in her bunker, fearing an alien invasion. She is also somehow attracted to the topic, " The War of 1812 ". Mrs. Byrne also uses old techniques/ways rather than using modern technology, like using carrier pigeons rather than e-mail.
