How we first met him: Leading his own group of survivors through the woods when they come upon a back way into the prison ("Made to Suffer")
How he died: Bitten by the zombified corpse of one of Noah's younger brothers, he dies while having hallucinatory visions of dead friends and foes like Bob and the Governor ("What Happened and What's Going On")
Why his death mattered: Tyreese left behind a sister and many friends, and also left an impression on the audience as someone who was simultaneously the most physically imposing of the show's heroes and one of its gentlest.
