"What Happened and What's Going On" is the ninth episode and mid-season premiere of the fifth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on February 8, 2015. It marks Chad L. Coleman's final appearance as series regular Tyreese. It also features several appearances from deceased characters in Tyreese's hallucinations. The episode was written by series showrunner Scott M. Gimple and directed by Greg Nicotero.
The narrative takes place in Richmond, Virginia, marking the first time the series is not set in Georgia. It takes place 17 days after Beth Greene's (Emily Kinney) death as the group finds Noah's walled community known as "Shirewilt Estates", a nod to a similar location in the comic book series. The episode primarily focuses on Tyreese, his struggle accepting death, and the guilt he faces over the losses of other group members due to actions he believes he could have done differently. The opening montage intercuts among a funeral that appears to be Beth's and previous sanctuaries: Woodbury, the prison, and Shirewilt. The ending reveals the funeral is Tyreese's. Several deceased characters return as hallucinations such as Martin (Chris Coy), Bob Stookey (Lawrence Gilliard Jr.), The Governor (David Morrissey), Lizzie and Mika Samuels (Brighton Sharbino and Kyla Kenedy), and Beth Greene. This episode also includes an acoustic cover version of Jimmy Cliff's "Struggling Man" sung by Beth.
The episode was lauded by television commentators, who praised Coleman's performance, Nicotero's direction, and Gimple's script. Others noted Tyreese's death as shocking and well-handled.
