After a member of Tyreese's group was bitten by a walker, he lead his group into the prison. Carl heard Tyreese and his group battling walkers, and he went to help them out. After helping Tyreese's group, Carl locked them up for the safety of his own group.
For TV viewers who want to find out more about Tyreese in the comic books, they will get their chance to next year for free. As part of Free Comic Book Day, Image Comic is providing comic book shops with The Walking Dead Special to giveaway.
The Walking Dead Special is written by Robert Kirkman with art by Charlie Adlard. The cover to the special is by Cliff Rathburn. The Walking Dead Special will contain a brand new Tyreese short story. It also reprints short stories featuring Michonne, The Governor and Morgan. The issue should be in high demand among Walking Dead fans, because none of the stories will be reprinted in the trade paperbacks.
The Walking Dead Special will be released on May 4, 2013 as part of Free Comic Book Day.
