One of the big mysteries about the “Home” episode of The Walking Dead was where exactly Tyreese and his group were when the Governor was attacking the prison. In fact, Tyreese and his group were not shown or mentioned during the entire episode.
During the Talking Dead, Walking Dead creator Robert Kirkman addressed where Tyreese’s group was. Robert Kirkman said, “They are not still in the prison. They left after Rick’s big episode at the end of the last episode.”
Robert Kirkman added, “But we don’t know where they are. Maybe, we’ll find out at some point in the future, maybe soon, maybe later.”
